I've been watching video clips on Youtube.com lately. My favourite videos all seem to have a central theme. The misfortune of others. I don't know why I find it funny when some random skater hurts himself trying to do some trick, or why I can't stop laughing when I see a little girl hit her dad with a stick in an attempt to crack a pinnata.
It just is. I like watching crashes, failed attempts at jumping over stuff and cars crashing. Youtube is way better than America's Funniest Videos ever was. Type in the key phrase "Funny Accident" and you'll be set for hours. With no repeats.
I do feel a little guilty laughing at the misfortune of others, but it's funny because I don't know them.
