A man was walking down the street when he was accosted
by a particularly dirty and shabby-looking homeless
man who asked him for a couple of dollars for dinner.
The man took out his wallet, extracted ten dollars and
asked, "If I give you this money, will you buy some
beer with it instead?" 

"No, I had to stop drinking years ago," the homeless
man replied.

"Will you use it to gamble instead of buying food?"
the man asked. 

"No, I don't gamble," the homeless man
said. "I need everything I can get just to stay
alive."

"Will you spend the on greens fees at a golf course
instead of food?" the man asked.

"Are you NUTS!" replied the homeless man. 
"I haven't played golf in 20 years!"

"Will you spend the money on a woman in the red light
district instead of food?" the man asked. 

"What disease would I get for ten lousy bucks?" exclaimed
the homeless man.

"Well," said the man, "I'm not going to give you the
money.  Instead, I'm going to take you home for a
terrific dinner cooked by my wife."

The homeless man was astounded.  "Won't your wife be
furious with you for doing that? I know I'm dirty,
and I probably smell pretty disgusting."

The man replied, "That's okay, I just want her to see
what a man looks like who's given up beer, gambling,
golf, and sex.
