A guy's in line at the supermarket when a blonde at the back of the line starts waving to him.
He doesn't recognize her, so he walks over and says, "I'm sorry, do I know you?"
She says, "I think you might be the father of one of my children."
He says, "Yow...are you the stripper from my bachelor party, who I banged on the pool table in front of all my friends while your girlfriend whipped me with wet celery and stuck a cucumber up my ass?"
She says, "No, I think I'm your son's English teacher."
