A guy goes to the supermarket and a beautiful blond woman waves at him and says hello.
He's rather taken back, because he can't place where he knows her from. So he asks, "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 bachelor party that I laid on the pool table with all my buddies watching,
while your partner whipped my ass with wet celery???"
She looks into his eyes and calmly says,
"No, I'm your son's maths teacher."
