Our parents have their own beliefs, and they'll often try to teach us to have the same.

Must we believe what our parents believe? Is it disrespectful to question it?

A big thank you to Hazel for this curly question!

You get an award at school, your dog learns a new trick, or your mum lands a great job – they're all moments we can be proud of.

When that pride swells inside, it makes us want to tell the whole world!

But is it being proud of yourself or just showing off? What's the difference?

Molly has never been afraid of getting a needle because she knows the Needle Ninja will reward her bravery with a basket of Japanese lollies, cakes and toys. Carl has never heard of this person and thinks Molly has been tricked by her mum and dad. But is there any harm in believing in the Needle Ninja? And is it OK for parents to tell their kids stories if it makes them feel better?

Why do some kids get all the luck? It doesn't seem fair that some kids are born into families with lots of love and support, while other kids don't get any, or don't have a family at all. The philosopher Plato had a pretty wild idea for how to fix this unfairness — get rid of families! He said if we did that, people would care more about all children, not just their own. What do you think? Would the world be a better and fairer place if we brought up children in a different way?

And special thanks to Oren Thaler, for telling us about his time growing up in the Kibbutz.

Do you have a teddy, a doll or a rug that is, or was, very important to you? We are told that as we grow up we need to get rid of ‘babyish’ things like that, but do we really? And if we lose our teddy or give it away, is it alright to feel sad about it? We hear about teddies and other things which were important to Molly, Carl and Matt and find out who kept theirs and why.

One of the best places to be on a hot summer's day is cooling off in a swimming pool. But until the 1960s Aboriginal people were not allowed to swim in the local pool in Moree, in country New South Wales. They were excluded because of a reason that had nothing to do with the ability to swim. They were excluded only because they were Aboriginal. So what is discrimination and what makes it bad?

Carl is excited because he saw a UFO last night. He can't believe it! (And neither can Molly, but for different reasons). But should we believe Carl and if not, why not? How do we decide if something is true or not? What sort of evidence do we need?

Molly, Carl and Matt become lost at sea, they've run out of food and they lack basic survival skills. So, would it be okay for them to eat each other if they get really really really hungry? Maybe don't listen to this episode while you're eating!

"Do as I say, not as I do!" Does this sound like the adults in your life? Short & Curly listeners often complain that their parents tell them to do one thing but then do something completely different themselves. So unfair! Or is it?

Guests:

Here's a question from Short & Curly listener Harvey: "Is it OK to hang out with your friends if they're being mean to other people?" Difficult, right? Have you been in a tricky situation like this? What's the best thing to do and why?

Molly has never been afraid of getting a needle because she knows the Needle Ninja will reward her bravery with a basket of Japanese lollies, cakes and toys. Carl has never heard of this person and thinks Molly has been tricked by her mum and dad. But is there any harm in believing in the Needle Ninja? And is it OK for parents to tell their kids stories if it makes them feel better?

Carl often gets lost when he's out on the streets alone. So the S&C team have decided a tracking device will keep him safe and sound. But is this a good idea? How do we balance safety with the need to become independent? And would you be okay with an adult putting a tracking device on you?

How much stuff do you have? How many toys, books, games and clothes you have got that you don't use or wear? Is it time to re-think why we give and receive birthday presents? Let's drop in to Molly's birthday party and find out.

Would you like to live forever? Molly and Carl like the idea of being immortal. The upsides: you won’t ever die, you’ll never run out of time to try new things and meet new people. The downsides: drinking blood and sleeping in a coffin, and your non-vampire friends will all leave you when they die. So, would immortality be worth it? And how can you make a decision about something so hugely different from any experience you’ve ever had before?

The Titanic cruise ship hit an iceberg in 1912 and sank to the bottom of the ocean. Lots of people died because there weren't enough life rafts for everyone. Women and children were offered seats on the lifeboats first because of their age and gender. But is that fair? Are the lives of kids more precious than the lives of adults?

To be good at sport you need both physical skills and mental strength. So is it okay to tease and sledge your sporting opponents to get an advantage? Join Molly and Carl for a game of backyard cricket.

Test your buzzers, put your Short and Curly thinking caps on and get ready for round one. Molly, Carl and Matt tackle some of the many questions you've emailed us, on the game show that's got everyone talking: Answer The Question!

Actors: Zali, Ngaio, Joel, Adam, Hannah and Jarvis.

Matt was so excited when he bought two pet fish and named them Bucket and Spade. It wasn't long though before one of those fish got sick. Very sick. The pet shop said he needed special chemicals for the water, so he spent a lot of money to make things better. Sadly, things didn't improve for Bucket. Or was it Spade? Anyway, did Matt do the right thing for his fish? And is a fish's life as important as other types of pets?

Some kids really want to get their ears pierced but their parents won’t let them. So, who should get to decide when and how you’re allowed to decorate your body with a piercing or even a tattoo? We get out the piercing gun and the tattoo ink and find out how much control we should have over our own bodies.

School uniforms have been around for hundreds of years but what's the point of them? Do they kill your individuality, or do they help you focus on learning, without all the worries about fashion and how you dress? We hear from children who wear uniforms and children who don't.

Robin Hood and his band of merry men of Sherwood forest reckoned rich people had it too good. So, they roamed around the countryside robbing the rich to give to the poor. Do you agree?

Molly Daniels thinks she has what it takes to be a superstar pop singer. The only trouble is, she's out of tune and can't hit the notes properly! Eek. But wait, there's a program many musicians use which "fixes" their voice. Is it wrong to use technology to make you sound better than you are?

We visit the bedroom of one of the messiest kids we know, Harriet. She hates cleaning her room more than anything in life and it always looks like someone opened every drawer and threw all the contents into the air. But is it her fault that her room is a pigsty? And if other kids can manage to keep their rooms tidy, why can’t Harriet?   

While Molly stays at home to fight crime and breed endangered lizards, Carl packs his toothbrush and some clean underwear for Short & Curly’s big adventure to New York City.

If someone does or says something bad to you, but then apologises for it, should you forgive them no matter what? Even if you don't really feel it in your heart?

Let's say you can hook your brain up to a machine that feels 100 per cent real and offers you the kind of life you've always wanted. You could climb one of the world's tallest mountains, get yourself some great friends, and even program in some challenges to keep it interesting. The catch is this perfect world isn't real… It's a simulation. Molly thinks it sounds cool, but isn't sure about leaving her real life dogs behind. The show takes us on a thought experiment to work out what it is we really want from life and what things are important.

Kids have to live by the rules of the society they are born into but don't get a say on what those rules are. Unfair, right? Decisions made by governments today affect kids' futures but we don't let them near the ballot box. Are children wise enough or informed enough to make big decisions about government? Short & Curly mounts our own political debate with surprising results. Guest Amara is a smart kid who doesn't think it's necessary. How would you vote?

Many cultures believe it's good luck if a bird poos on your head, like what happened to Carl (eww!). Others say it's bad luck if you break a mirror. For centuries, humans have tried to understand things like right and wrong, fair and unfair. So, how much does luck play in your life, in good or bad ways? And how might understanding luck make us think differently about the world?

What would you do if you had the power of invisibility? Would you sneak around, spy on people, commit crimes, pull practical jokes, or find out what other people really think about you? The military is putting tonnes of money and effort into trying to make things invisible, but don't hold your breath. We introduce a new superhero, Invisibilia, to help us explore some really big questions. How would you behave if you thought no-one could see you? Is it about doing the right thing or is it the "getting caught" part that stops bad behaviour?

Lollies are a colourful and magical and very sweet part of many children’s lives. But can you say no when faced with a bowl of jelly beans or sour worms or other types of candy? With so much concern nowadays about the amount of sugar in our diets, this show looks at self control and what we should do if people don’t have any.

Walked into any traffic lights lately as you stare manically at a screen? Maybe you’re one of the millions of people playing Pokemon Go, the augmented reality game which sends its players out into the streets to catch weird little imaginary creatures. Is it an annoying disruption of public spaces? And, because it’s cleverly designed so you never want to stop playing, we ask: Are you playing the game or is the game playing you?

Images of movie stars and pop singers are everywhere we look – album covers, concert posters, t-shirts, Instagram feeds and other social media. Photos and videos are a big part of how famous people present themselves. But, how honest and accurate are they? Do they look anything like they do in real life… and should they? When do small changes to an image turn it into a lie? And does it even matter?

For professional fire and rescue workers, it’s not all sirens, cool trucks and running red lights. They often have to make really hard and terrible decisions in moments of heat, smoke and danger. Their job is to be there to help on the worst day of your life. So, if you were a firefighter, who would you save first?

We’re often told we have a special responsibility to our brothers and sisters just because they are family. But, do we really? And what kind of duty is it?  What if you found out the annoying new kid at school was your long lost brother or sister?  Would you feel any differently about them? And, if you really didn’t like them, is it somehow worse to kill a sibling than to kill anyone else? Yep, some murderously tricky questions!

Unless you’re a vegetarian, there are some animals you probably eat regularly.  But how would you cope if your next dinner was some stir-fried dog?  Why is it okay to eat a baby cow (veal) or sheep (lamb) and not a cute little puppy?  Are our ideas about eating animals a bit of a mess?  And does this matter?

He is wise and old and learned and kind, but the Principal of Hogwarts is not perfect.  He deceives, he holds back really important information about issues of life and death, and is willing to sacrifice Harry Potter for the good of the many, leading him (as Professor Snape says) “like a pig to slaughter”.  So, is Dumbledore an ethical person?  How flawed are we allowed to be and still be counted as “good”?

There are 1,000 people currently shortlisted for the trip of a lifetime, from which they will never return!  They want to be the first stage in the human habitation of the red planet.  But do humans have a right to inhabit other planets, and which humans specifically?  Would colonizing Mars be a chance to create a better world from scratch, or will it become an environmental and ethical nightmare?  Would you want to go?

Kind lies. White lies. Little lies. We take a trip to the fun park to look at all sorts of lies we tell for all sorts of reasons. Like what if your parent asks you to pretend to be younger than you are to get a cheaper entry fee? What’s the right thing to do? Amidst the rides and games, junk food and excitement, we explore a few stories about lying, a subject which has divided some of the greatest thinkers in history.

In the 1950s, a group of young boys took part in a now famous experiment to find out how easy it would be to turn two groups of children into enemies. The boys didn’t know they were in a scientific study, and many later regretted the things they did to each other. Is the knowledge we might get from such an experiment worth the pain it might cause to get it?

Imagine if you were being watched every second of the day to make sure you behaved well. And then you got rewarded or punished depending on how you acted? In this episode, we take a long hard look at Santa Claus, because news flash, we are told he's watching you day and night.

Meet Oedipus. He's the main character in one of the world’s oldest stories. He lived a long time ago and he did some pretty bad things. But was it his fault or was it fate? Was there anything he could have done to avoid tragedy? Join Molly, Carl and Matt as they sing their way through an ancient tale of terrible misfortune. 

Molly, Carl and Matt become lost at sea, they've run out of food and they lack basic survival skills. So, would it be okay for them to eat each other if they get really really really hungry? Maybe don't listen to this episode while you're eating!

This season we go on a little adventure in our minds. Join Molly, Carl and Matt as we imagine what the world might be like without things like schools and sadness and punishment. Would everything be better without them?

Imagine if something private you told a friend could be shouted out for the whole world to hear? Or if an embarrassing bodily function was shared with everyone? Some people say privacy is only necessary if you have something to hide, but are there other reasons to keep certain things just for yourself?

There's nothing like munching on your favourite snacks and watching all your favourite shows and movies. You're not making lots of noise or bothering anyone too.

So, why can't you watch TV all day?

Thank you to Amelia and Evie for the great question!

We often feel sadness and heartbreak when something bad happens, like when a much-loved pet dies or someone at school doesn't want to be friends anymore. Or even when your sports team loses the grand final after you've trained really hard for it. Would life be better if you could magically make that sadness disappear?

What's the point of school anyway? That's a question lots of you have written to us to ask. Nearly every day of the week for years and years and years, you have to get up, put your uniform on and go to a big building full of other children, just so you can learn stuff. And then once you're in the school building, grownups get to decide when you're allowed to eat your lunch and when you're allowed to play. It's tiring and sometimes boring. So should we just get rid of schools?

What if there was no fine for letting your dog poo on the footpath? No consequences for hitting your brother or sister? And teachers never gave detention for breaking a school rule? If we lived in a world without punishment, would we all start just doing whatever we wanted? Or are there better ways to deal with people doing the wrong thing?
