Biology lesson


Lantern Swinger
A biology professor at the University of Australia 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 asked, "Do you know what
your ******** is doing while you're having an orgasm?"

"Probably out fishing with his mates!!" she replied.
