A guy is walking along when he encounters a bum.
The bum asks the man for $2.

The man asked, "Will you buy booze?"
The bum said, "No."

The man asked, "Will you gamble it away?"
The bum said, "No."

The guy says, "Ok pal, here's FIFTY DOLLARS if you'll come home with me so my wife can see what happens to a man who doesn't drink or gamble!"
