today in java the prof asked the class for a simple iterator where we canĀ  use some math so this one guy pipes up and says "Make it an address book, and It will calcuate the percentage of girls that slept with you" the prof looks up and says "I can't do that", meaning its not appropriate so the guy yells back "why not?" and the first thing that came to mind i said "You get an error when you divide by zero"
