Professor Higgins at the University of Sydney was giving a lecture on 'Involuntary Muscle Contraction' to a group of first year medical students.
This was not an exciting subject and 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 arse hole is doing while you're having an orgasm?'
She replied, 'Probably out playing golf with his mates.'
It took 45 minutes to restore order in the classroom!
Ed. Abnormal service will resume on Monday. (That’s if I survive major dental work scheduled for 11.30).
