A professor at MEMORIAL UNIVERSITY OF NEWFOUNDLAND, 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 asshole is doing while you're having an orgasm?'
She replied, 'Probably deer hunting with his buddies.'
