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 give you this money will you take it and buy whiskey?"

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

"Will, you use it to gamble?"

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

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

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

The man said "Well I'm not going to give you the 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 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."
