PROFESSOR OF MATHEMATICS

A professor of mathematics sent a fax to his
wife. It read: "Dear Wife: You must realize
that you are 54 years old, and I have certain
needs which you are no longer able to satisfy.
I am otherwise happy with you as wife, and I
sincerely hope you will not be hurt or offended
to learn that by the time you receive this letter,
I will be at the Grand Hotel with my 18-year-old
teaching assistant. I'll be home before midnight.
-Your Husband"

When he arrived at the hotel, there was a faxed
letter waiting for him that read as follows:
"Dear Husband: You, too, are 54 years old, and by
the time you receive this letter, I will be at
the Breakwater Hotel with the 18- year-old pool
boy. Being the brilliant mathematician that you
are, you can easily appreciate the fact that 18
goes into 54 a lot more times than 54 goes into
18. Don't wait up."
