A blonde, brunette, and a redhead are all running from the cops. They're driving down the road when they spot three sacks on the side of the road. They all hop out and each one jumps into a sack to hide. The cops pull up and decide to inspect the bags. A cop walks up to the first one, kicks the sack, and the redhead says "bark bark bark!"
Cop: This sack is full of puppies!
So he moves to the next sack, kicks it, and the redhead says "Meow meow meow!"
Cop: This sack is full of kittens!
He finally moves to the third sack, kicks it, and the blonde says "Po-ta-to, po-ta-to, po-ta-to!"
Guess who gets caught?
