This is an old one.
Four friends reunited at a party after thirty years. After a few
laughs and drinks, one of them left to visit the rest room. The
others began to talk about their kids and their successes.
The first man said, "I am really proud of my son; he is my pride
and joy. He started working at the bottom of a very successful
company. He studied economics and business administration, and he was
soon promoted and began to climb the corporate ladder, becoming the
general manager. Now he is the president of the company. He is so rich
that he could afford to give his best friend a top-of-the-line Mercedes
Benz for his birthday."
The second man said, "Wow, that's terrific! My son also is my
pride and joy, I am very proud of him. He started working at a travel
agency for a big airline. He went to flight school to become a pilot and
also managed to become a partner in the company where he now owns a
majority of the assets. He became so rich that he recently gave his best
friend a brand new jet for his birthday."
The third man said, "Well, well, congratulations! My son is also
my pride and the apple of my eye and he is also wealthy. He studied
in the best universities and became an engineer. He started his own
construction company and became quite successful and a multimillionaire.
He too gave away something very nice and expensive to his best friend for
his birthday -- he gave him a 30,000 sq ft mansion built especially
for his friend."
The three friends congratulated each other mutually for the successes of
their sons. The fourth friend who had gone to the restroom returned
and asked, "What is going on -- what are all the congratulations for?"
One of the three explained, "We were talking about the mutual
pride we feel for the successes of our sons." And then he asked, "What
about your son?"
The fourth man replied, "My son is gay and he makes a living dancing as
a stripper at a nightclub." The three friends commiserated, "What a
shame -- that must be horrible for you. What disappointment you must
feel." The fourth man replied, "Oh no, I am not ashamed. Not at all. He
is my son and I love him well. He is my pride and joy, and he is very
fortunate, too. Did you know that his birthday just passed and the other
day he received a brand new jet, a beautiful 30,000 sq ft mansion, and a
top-of-the-line Mercedes Benz from his three boyfriends."

That one is always a classic!
