A little old lady was walking down the  street dragging two large plastic garbage bags behind her onto the  sidewalk.
Noticing this, a policeman stopped her  and said, "Ma'am, there are $20 bills falling out of that bag."
"Oh, really? Darn it!" said the little  old lady. "I'd better go back and see if I can find them.  Thanks for telling me, officer."
"Well, now, not so fast," said the  cop. "Where did you get all that money?  You didn't steal it, did you?"
"Oh, no, no", said the old lady. "You  see, my backyard is next to a golf  course. A  lot of golfers come and pee through a  knothole in my fence,  right into my flower garden. It used to really tick  me off... kills the flowers, you
know. Then I thought, 'Why not make the best of it?' So now, I  stand behind the  fence by the knothole, real quiet, with my hedge  clippers  and every time some guy sticks his "thing" through my fence, I  grab hold of it and say, "OK,
buddy!  Give me $20 or off it comes!"
"That seems only fair," said the cop, laughing. "OK. Good luck! Oh, by the way, what's in the other bag?"
"Not everybody pays."
