let's revive this topic because i found a good joke..

A guy goes to the supermarket and notices a very attractive 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 races. He racks his
brain and travels back to the only time he has ever been unfaithful to his
wife and says, "My God, are you the stripper from Fred's stag night that I
fucked on the pool table with all my buddies watching, while your
partner whipped me with wet celery???"

She looks into his eyes and calmly says, "No, I'm your son's Grade 3
teacher"
