The college professor had just finished explaining an important
research project to his class.

He emphasized that this paper was
an absolute requirement for passing his class, and that there
would be only two acceptable excuses for being late.

Those were
a medically certifiable illness or a death in the student's
immediate family.

A smart ass student in the back of the classroom
waved his hand and spoke up.

"But what about extreme sexual exhaustion, professor?"

As you would expect, the class exploded in laughter.

When the
students had finally settled down, the professor froze the young man
with a glaring look.

"Well," he responded, "I guess you'll just have to learn to write with
your other hand."
