My philosophy joke: Plato gets pulled over for speeding. He rolls down the window for the cop; the cop, eyeing Plato's toga, assumes he's dealing with a delinquent frat boy. ""You thought you'd get away doing 90 in a 65? What do you take me for, a fool?"" Plato looks up: ""Of course notclearly I'm the fool, officer."" So the cop makes him walk the divided line.

Why did Plato's worst student always have stuff stuck in his teeth? He didn't understand Flossophy!
