I just found out a little thing about Norway (where I'm from).
There is actually a law forbidding taking pictures of yourself wearing a diaper or dressed like a person under 18 years old (of course only sexual pictures), and distributing it in any way!
If you break this law, you may be jailed for 3-5 years or get a fine for it from 6000$ and up-up-up.
Why, you ask? Well... It's because it's considered as child pornography...(!)
Isn't that stupid?
