The Pessimist: What's this? Dang! I forgot to shave my right leg.
The Optimist: Hey, but the left one is verrrrry smooth.
The Theorist: Hmmm, maybe I shaved the left one twice?
The Realist: Holy Crap! I was supposed to be at school five minutes ago!
Peace (if there is such to be had in this legs-are-half-shaved kind of world)
