A man was walking in the city, when he was accosted by a particularly dirty and shabby-looking bum who asked him for a couple of dollars for dinner.

The man took out his wallet, extracted two dollars and asked, "If I gave you this money, will you take it and buy whiskey?"

"No, I stopped drinking years ago," the bum said.

"Will you use it to gamble?"

"I don't gamble. I need everything I can get just to stay alive."

"Will you spend the money on greens fees at a golf course?"

"Are you NUTS! I haven't played golf in 20 years!"

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

The bum was astounded.

"Won't your wife be furious with you for doing that? I know I'm dirty, and I probably smell pretty bad."

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