duh!

Haven't had a moment to spare people...in the mean time, i thought this one was hilarious!! enjai!

A guy goes to the supermarket and notices a beautiful blonde 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?" and she replies, "I think you're the father of one of my kids."
His mind races 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 laid on the pool table with all my buddies watching, while your partner whipped my butt with wet celery and then stuck a carrot up my butt???"
She looks into his eyes and calmly says,

"No, I'm your son's maths teacher."
