A guy goes to the supermarket and notices an attractive woman
waving at him. She says hello. He's rather taken a back 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 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 I made love to on the pool table with all my
buddies watching while your partner whipped my butt with wet
celery??? '
She looks into his eyes and says calmly, 'No, I'm your son's
teacher. '
