A Professor was giving a lecture on 'Involuntary Muscular
Contractions' to his first year medical students.
Realising 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 arse hole is doing while you're having an
orgasm?'
She replied, 'Probably fishing & drinking beer with his
mates.'
The professor laughed so much he could not continue with the
lecture.
