A guy goes into a supermarket and notices a beautiful blonde who waves at him and says hello. He's rather taken aback because he
doesn't recognize her and aks, "Do you know me?"
To which she replies, "I think you are the father of one of my kids."
He panics, and thinks of the only time he was unfaithful to his wife and says, "OMG!! Are you the stripper that was at my bachelor
party that I put on the pool table while all of my buddies watched and then you and your friend covered me in whipped cream and
licked it all off?"
The woman looks at him, eyes wide and responds, "No, I'm your son's math teacher."
