A guys goes to the supermarket and notices a very beautiful lady wave at him and say hello.

He is rather surprised, because he cannot seem to remember where he had met her.

So he says,”do you know me?” to which she replies “i think you are the father of one of my kids”.

Now his mind travels back to the only time he has ever cheated on his wife and says ” my God!! are you the stripper from my bachelor party that i had sex with on the pool table with all my guys watching, while your partner whipped my butt with wet celery????

she looks into his eyes and calmly says, “no, i am your son’s math teacher”
