A high-school English teacher reminded her class of the final
exam that would be given the following day. She told the class
that there would be no excuse for not showing up, except for
serious injury or illness, or a death in the student’s immediate
family. A smart-ass jock in the back of the room asked, “What
about extreme sexual exhaustion?” The entire class did its best
to stifle their laughter and snickering.

When silence was restored, the teacher smiled sympathetically
at the student, shook her head, and sweetly said, “Not an excuse.
You can write with your other hand.”
