A professor at the University of Wisconsin 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 asked, "Do you
know what your butthole is doing while you're having an orgasm?"
She replied, "Probably playing golf!"
End of lecture.
