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 of dinner?"
"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 20years!"
"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. It's important for her to see what a man looks like after he has given up beer, gambling, golf, and sex."
