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 azz hole is doing while you're having an orgasm?"

She replied, "Probably deer hunting with
his buddies".

Lol. I know the real answer

yea, what was she thinking..
