Saw this on another site:

A little Jamaican old lady is walking down King
Street dragging two large plastic garbage bags behind her.
One of the bags rips, and every once in a while a $100 bill
falls out onto the sidewalk.

Noticing this, a policeman stops her, and says,
"Hey missis, yu doan see money a fall outta yu bag
dem?"

"Lawd mi Gawd!" says the little old lady.
"Mi have fi go back an fin' dem!" Tenks fi
telling mi."

"Hold dung! Not so fast," says the cop.
"Is whey yu get di money from? Is steal it yu
steal it?"?

"Oh, no sah", says the little old lady.
"You see, fi mi back yard a right next to the stadium
parking lot. Any time a match a gwaan, whole heap a fans dem

"Well, dat sound fair" laughs the cop.
