MATH LESSON

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."
