Joke A professor was giving a lecture on "Involuntary Muscular Contractions" to 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 arse-hole is doing while you're having an orgasm?" She replied, "He's probably down at the pub with his mates."
