A pretty girl walks into a mathematician's and engineer's lab... ... and says she will bang whichever of them shows the most athletic or intelligent talent. Since they are equally smart, they decide to go 3/5 on a few different exercises at the gym. The first exercise is chin-ups, which the engineer wins. The second is long jump, which the mathematician wins. The third is squats, which the engineer fails in a matter of seconds. It is clear to the engineer when the reach the fourth event, short dash, that he has no hope of winning. Eagerly, the mathematician says "Where to?" The engineer knows he can't run very far, so he says "just to the door." The door is on the farthest end of the gym. The engineer knows he's beat, but does the challenge anyways. The girl shouts 'GO!' and they run as fast as they can. The engineer gets a bit of a lead, but falls behind the mathematician eventually. finally, the mathematician runs out the door and yells "YES! I WIN!" Then he looks around to the engineer, who locks the door.
