A guy goes to the supermarket and notices a very attractive woman waving at
She says, 'Hello.'
He's rather taken aback because he can't place where he knows her from. So
he sheepishly asks, 'Do you know me?'
To which she replies, 'I think you're the father of one of my kids.'
Now, in a flashback, his mind travels back in time and tries to remember when
it may have occurred.
So he asks, '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.’
