Phisiology

[GTDADDY]

Professor Higgins at the University of Sydney was giving
a lecture on 'Involuntary Muscle Contraction' to
first year medical students.
It was not an exciting subject so the professor decided to
lighten up the mood. He pointed to a young woman in
the front row and asked, 'Do you know what your asshole
is doing while you're having an orgasm?'

She replied, 'Probably golfing with his buddies.’
