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 asshole is doing while you’re
having an orgasm?”
She replied, “Probably deer hunting with his buddies.”
The professor laughed so hard he could not continue with the class.
