A little old lady was walking down the street dragging two large plastic
garbage bags behind her. One of the bags rips, and every once in a while a $20 note falls out onto the sidewalk.
Noticing this, a policeman stops her, and says, "Ma'am, there are $20
notes falling out of your bag."
"Oh, really? Damn it!" said the little old lady. "I'd better go back, and
see if I can find them. Thanks for telling me."
"Well, now, not so fast," says the cop. "How did you get all that money?
"You didn't steal it, did you?"
"Oh, no", said the little old lady. "You see, my back yard is right next
to the football stadium parking lot. On game days, a lot of fans come and
pee through the fence into my flower garden. So, I stand behind the fence
with my hedge clippers. Each time a guy sticks his thing through the
fence, I say, '$20 or off it comes'.
"Well, that seems only fair" laughs the cop. "OK. Good luck! Oh, by the
way, what's in the other bag?"
"Well, you know", "not everybody pays".
