This guy is in line

This guy is in line at the Super Market when he notices a hot blonde behind him has just raised her hand and smiled hello to him. He is stunned that such a hottie would be waving to him, and although familiar he can't place where he might know her from, so he says "Sorry, do you know me?" She replies "I may be mistaken, but I thought you might be the father of one of my children!" His mind remembers back to the one and only time he has been unfaithful to his wife, "Christ!" he says, "Are you that stripper at my bachelor party I had on the pool table in front of all my friends, while your partner whipped me with wet celery and stuck a cucumber up my ass?" "No" she coldly replied, "I'm your son's English Teacher."
