IT is only because of violence that are shown on TV. All cartoons for kids are based on violence mostly. For example famous Tom and mouse Jerry or smth. ****** up next generation!! HURRAY!

actually the root of laughing comes from a primates 'fear call' when people laugh it is mainly to say "I am not a danger to you", or out of shock, aka why the children laughed the laughs in a primitive time would be considered a warning to anyone else around that bad things can happen and to be careful... laughing then evolved so people laugh for other reasons and it makes us feel good because of the endorphins released... so although you didn't feel good they were warning others and each other, on a primitive level anyway... little bit of psychology...

okay.

Havent u watched spongebob, he beat up himself like hell to make the kids laugh

Well duh. Spongebob taught me that. :D

I love the word "Toddler" :')

Haven't you seen that Sponge Bob episode? Of course kids love to laugh at other people's pain. And most other people....

That happen in spongebob too!!

Pinkie Pie?

Same thing happened to me when I was babysitting this one year old. He jerked and hit his head on his crib bars when I was trying to safely put him in his crib. I called his uncle to come help me put him to sleep. Next thing you know, I'm trying to get the toddler to sleep when he decides to punish me by repeatedly throwing a crumpled, up, plastic water bottle at my head. Even more depressing, it was the funniest thing that had happened to me that day.
