Annoyed by the professor of anatomy who liked to
tell "naughty" stories during class, a group of
female students decided that the next time he
started to tell one, they would all rise and leave
the room in protest.

The professor, however, got wind of their scheme
just before class the following day, so he bided
his time. Then, halfway through the lecture, he
began."They say there is quite a shortage of
prostitutes in France."

The girls looked at one another, arose and started
for the door.

"Young ladies," said the professor with a broad
smile, "the next plane doesn't leave till
tomorrow afternoon."
