The following was told to me by a fellow Morris Man, who claims that
it is true and that it was related to him by a teacher at Melbourne
Grammar.

The teacher has set the class an assignment. He stresses the
importance of the particular assignment, and that no excuses will be
accepted except illness (with a medical certificate) or a death in
the immediate family (with a note from that member).

A smart-ass student pipes up: What about extreme sexual exhaustion,
sir?

The class breaks up laughing, and when they settle down the teacher
responds with:

Well, Jones, I guess youll have to learn to write with your other
hand.
