A high school English teacher reminds her class of tomorrow's final exam.

She tells the class there would be no excuse for not showing up, except for serious injury, illness or a death in the immediate family.

A smart-ass jock in the back of the room asks, "What about extreme sexual exhaustion?" The entire class bursts into laughter.

When silence is restored, the teacher smiles sympathetically and sweetly says,

"Not an excuse. Write with your other hand."
