This is what you say after you punch and/or kick a guy in the balls. This is a good revenge to use on douchebags. Here's what you do:

Knock on douchebag's door.

When douchebag answers, come at him like a spider monkey- a deranged, rabid spider monkey.

Punch/kick him right in the nuts.

As he writhes on the floor and cries, "Whhhhyyyy??!?!?!", You point at him and yell very scarily, "YOU KNOW WHY!!"

And he will know why.

Revenge accomplished!
How to correctly carry out a "you know why."

Dave (answers door): Oh, hi..
(Sara, crazy eyes and all, punches Dave in the nutsack)
Dave (falling to the floor): WWWWWHYY?
Sara: YOU KNOW WHY!
