Three Blonds are running from the law. They are being pursued by police and run into a barn where the only places to hide are in some burlap sacks. When the police come in they only see three burlap sacks so the cop kicks the first one.
"Meow Meow" says the first girl
"Aww just a cat" says the cop. He then goes and kicks the second bag.
"Woof Woof" says the second girl.
"It's just a dog" the cop says. Then goes to the third bag, and kicks it. Nothing. He kicks it again.
"Potatoes" Says the third girl.
