A guy goes to the supermarket and notices a beautiful woman wave at
him and say hello.
He's rather taken aback, because he can't place where he knows her
from.So he says, "Do you know me?"
To which she replies,"I think you're the father of one of my kids."
Now his mind travels back to the only time he has ever
been unfaithful to
his wife and says,"My God, are you the stripper from my stag
party that I made love to on the pool table with all my pals
watching,while your partner whipped my butt with wet celery???"
She looks into his eyes and calmly says, "No, I'm your son's
math teacher."
