A college professor had just finished explaining an important research project to his class. He emphasized that this paper was an absolute requirement for passing the class and there would only be 2 acceptable excuses for being late. Those were a medically certifiable illness or death in the family.
A smart ass in the class waved his hand and spoke up " But what about EXTREME sexual exhaustion, Professor?" As you would expect, the whole class exploded with laughter.
When the class FINALLY settled down, the professor froze the young man with a glaring look and said " Well, I guess you'll just have to learn to write with the other hand"
