Bob and his friend, Nick, rob a bank and all they get away with are two sacks, so they keep one each.

After awhile they meet again and Bob asks Nick, "What did you find in your sack?"

"Half a million."

"Wow, that's a lot! What did you do with the cash?"

"I bought a house. How about your sack, Bob?"

"I didn't do as good as you, mine was full of bills."

"And what did you do with them?"

"Well, little by little, I'm paying them off . . ."
