A policeman sees a little old lady walking down a city street, dragging two plastic garbage bags. While he is watching her, he observes that there is a hole in one of the bags, and every once in a while a £20 note flies out of it onto the pavement. As she goes to pass him, the policeman stops her. “Excuse me ma’am, but did you know there are £20 notes falling out of that bag?” “Dear me!” says the little old lady. “I had better go back and see if I can still find some. Thanks for the warning officer.” “Well now, not so fast. How did you get all that money? Did you steal it?” “Oh, no,” says the little old lady. “You see me back garden backs up to the stadium parking area. After each football game, a lot of fans pee in me hedges, right into me flower beds! So, I go and stand behind the bushes with a big hedge clipper, and say, ‘£20 or off it comes!'” “Fair play!” laughs the officer. “Well good luck. By the way, what’s in the other bag?” “Oh that,” the little old lady replies, “not all of them pay.”
