The teacher has given the class an assignment. He stresses the importance
of this 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). 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, I guess youll have to learn to write with your
other hand.
