A blond, a brunette, and a red head are being chased. They run into a barn, and find three sacks to hide in. Their pursuers find the first sack with the brunette hiding in it. Poking it, they hear, "Meow," and decide it is just a cat. Poking the second sack with the red head in it, they hear, "Woof," and decide it is just a dog. When they poke the last sack with the blond, they hear, "Potato."
