Two bag lady

A little old lady dragged two large plastic garbage bags behind her.
One was ripped by now, and once in a while a $20 bill fell out on the sidewalk.

A cop came up: "Ma'am, there are $20 bills falling out of that bag."
"Oh really? Darn it!" she said. "Thanks for telling me, I'd better go look for them."

Not so fast," said the cop. Where did you get that money? You didn't steal it, did you?"
"Oh, no, no", said the 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 a hole in the fence, right into my flower garden.
It really ticks me off. Kills the flowers, you know.

So now on game days I stand behind the fence by the hole, real quiet, with my hedge clippers ready.
Every time some guy sticks his thing through my fence, I surprise him, grab hold of it and say,
'O.K., buddy! Give me $20, or off it comes.'

"Well, that seems only fair," said the cop, laughing. "OK. Good luck!"
" Oh, by the way, what's in the other bag?"
"Well, you know", said the little old lady, "not everybody pays."
