A married man in his forties stops off at a supermarket to grab a few essentials on the way home from work.
As he stands in the line for the checkout, he notices an attractive lady, smiling and waving at him in the next line.
He's rather taken back by this, as he don't seem to recognize her, so he asks "do I know you"
You're the father of one of my kids, she replies.
His mind wanders back to the one time that he was unfaithful to his wife and he says "so you must be that stripper at my friends stag party, who dressed as a police woman and spent the night with me in my hotel room, boy I was so drunk!"
With a very red face, she replied.....".No, I teach your son".
