A teacher reminded her pupils of tomorrow's exam. 'Now listen to me, 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 but that's it, no other excuses whatsoever!' A smart-arsed guy at the back of the room raised his hand & asked, 'What would happen if I came in tomorrow suffering from complete & utter sexual exhaustion?' The entire class was reduced to laughter & s******ing. When silence was restored, the teacher smiled knowingly at the student, shook her head & sweetly said, 'Well, I suppose you'd have to write with your other hand'.
