A guy goes to the supermarket and notices a beautiful blond 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?"

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 tied me to the the pool table, gagged me with your sequined bra, shaved my pubes, while your partner whipped my butt with wet celery? My buddies still laugh themselves senseless over that night!
