A couple of dollars...

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 this 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 going to give you the money, and I am also 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 drinking, gambling, golf, and sex."(Hindsoe.com)
