Comedy is a mysterious thing. Why do people find some things funny, and others not? What makes something inherently funny? And why do so many people find disgusting things hilarious? When I was young, I remember seeing a shift from good cartoons to stuff that just grossed me out... and made everyone else laugh. Ren & Stimpy, anyone? And it's always baffled me. What is so amusing about dipping a live bunny into molten chocolate and eating the screaming remains before it dies? I don't know, but my facebook friends loved it.
Oh, and don't even get me started on the Year of the Dead Baby Jokes. I banned anyone from telling me those. Hate them. So much.
