A college teacher reminds her class of their upcoming final exam. "Now class, I won't tolerate any excuses for you not being here tomorrow. I
might consider a nuclear attack or a serious personal injury, illness, or a death in your immediate family, but
that's it. No other excuses whatsoever!"

A clever fellow in the back of the room raises his hand and asks, "What would you say if tomorrow I said I was suffering from complete and utter sexual exhaustion?"

The teacher smiles knowingly at the student, shakes her head and sweetly says, "Well, I guess you'd
have to write with your other hand."
