Involuntary Muscle Contractions A Professor was giving a lecture on "Involuntary Muscular Contractions"to his first year medical students. Realizing that 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 *** hole is doing while you're having an orgasm?" She replied, "Probably drinking with his buddies." The professor laughed so hard he could not continue with the lecture.
