There was a red head, a blond, and a brunette running from the cops, and they come across an old abandon house. They run inside, and the brunette sees 3 burlap sacks.
She picks it up and puts it on over her head, huddles in the corner, and says meow, meow, meow. So the cops come in the house and go up to the bag, and kicked it, and say, "It must be a bag of kittens", and they move on.
The red head grabs another one of the sacks pulls it over her head, huddles in the corner, and says woof, woof, woof. The cops walk by, and shine the flashlight on them, kicked the bag, and say, "It must be a bag of puppies." They move on.
The blond grabs the last sack, puts it over her head, and huddles in the corner. She starts saying potatoes, potatoes, potatoes.
(Ha ha ha..)
