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?"

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 as ever been unfaithful to his wife and says,"My God, are you the stripper from my bachelor
party that I laid on the pool table with all my
buddies watching, while your partner whipped
my butt with wet celery???"

She looks into his eyes and calmly says, "No, I'm your son's math teacher."
