Found on the Refrigerator One Morning :

My Dear Wife,

You will surely understand that I have certain needs that you, being 54
years old, can no longer satisfy. I am very happy with you and I value
as a good wife. Therefore, after reading this letter, I hope that you will not wrongly interpret the fact that I will be spending the evening
with my
18 year old secretary at the Comfort Inn Hotel. Please don't be
shall be home before midnight.
When the man came homelate that night, he found the following letter on the dining room table:

My Dear Husband,

I received your letter and thank you for your honesty
about my being 54
years old. I would like to take this opportunity to
remind you that you are
also 54 years old. As you know, I am a math
teacher at our local college. I
would like to inform you that while you
read this, I will be at the Hotel
Fiesta with Michael, one of my
students, who is also the assistant tennis
coach. He is young, virile,
and like your secretary, is 18 years old.
As a successful businessman who has an excellent knowledge of math, you
will understand that we are in the same situation, although with one small
difference - 18 goes into 54 a lot more times than 54 goes into 18.
Therefore, I will not be home until sometime
