A Professor was giving a lecture on 'Involuntary Muscular Contractions' to his first year medical students at the Indiana School of Medicine on the campus at Bloomington.

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'. He laughed so hard he couldn't finish teaching the class and sent them all home.

that is good thanks

Just sent forward to have the medical staff at the U of MN Hospital
