A college class is taking an exam when the professor says the time is up.
Johnny keeps writing and when he goes up to hand it in the professor tells him it is too late and he will have to take a zero.
Johnny looks at the professor and says, "do you know who I am?"
The professor looks at Johnny says "I have absolutely no idea."
Johnny, without skipping a beat, lifts up the pile of papers, shoves his in halfway down and walks away.
There is a life lesson in there somewhere.
