Kittens and are probably one of the funniest things to watch. Their curiosity will often get them into a situation where they aren't sure how to get out. Take this kitten. It's curiosity got it stuck inside a jar. I dare you to watch this video without laughing.

They say curiosity killed the cat, well in this case, it only humiliated the kitten. I swear I can sit and watch kittens play all day, unfortunately I'm allergic to them, so I have to enjoy them from afar.
