A guy goes into a supermarket and while walking down one aisle, a beautiful blond at the end of the aisle waves at him and says, “Hello”.
He’s rather taken back, because he can’t place where he knows her. So he says “do you know me?”
To which she replies, “I think you’re the father of one of my children.”
Now he thinks back to the only time he has ever been unfaithful 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 friend whipped me?”
“Afraid not” she said, ” I’m your son’s English teacher.”
