“Well now, not so fast,” says the policeman. “How did you get all that money? Did you steal it?”
“Oh, no”, says the little old lady. “You see, my back garden backs up to the parking area of the football stadium. Each time there’s a game, a lot of fans come and pee in the bushes, right into my flower beds!”
The little old lady continued…

“Hey, not a bad idea!” laughs the policeman.
“Well good luck”, he says to the little old lady, then adds “By the way, what’s in the other bag?”
“Oh that”, the little old lady replies, “not all of them pay up…”
