A professor at the University of Mississippi was giving a lecture on 'Involuntary Muscular Contractions' to his first year medical students. Realizing this was not the most riveting subject, the professor decided to lighten the mood slightly.

He pointed to a young woman in the front row and said, "Do you know what your ass hole is doing while you're having an orgasm?"

She replied, "Probably riding motorcycles with his buddies."
