Jon Stewart on teen sex (with a pie chart next to him):

61% of high school seniors already have had sex, while 37% will eventually have sex and the remaining 2% will become statisticians who design pie charts.

* Too bad I couldn't copy the image from the video player, it was hilarious. =) But if you want to watch it, it's called "Abstinence of Malice", thanks to Dave who pointed out that Jon Stewart was bagging on us.
