A guy goes to the super market, and notice a beautiful blonde who waves at him and waves a hello. He'd rather taken back because he can't place what he knows her from, so he asked her "do you know me?" To which she replies " I think your the father of one of my kids." Now he thinks back to the only time, he has ever been unfaithful to his wife and says " Oh my god are you the stripper from my bachelor party that I laid in the pool table with all my buddies watching, while your partner whipped me with a wet celery and then stuck a carrot in my butt?"

"No I'm your son's math teacher!"
