A guy goes to the supermarket and notices an attractive woman waving at
him.
She says 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 travels back to the only time he has ever been unfaithful to
his wife and says, '
Are you the stripper from the 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.'
