Three girls were on the run from the cops - a red head, a brunette, and a blonde. During the subsequent high speed chase the red head spotted a potato farm and suggested that the girls should hide out there.
Once at the farm all three girls girls climbed into a potato sack. The cops came to the potato farm, looked around, but saw no sign of the girls. The sheriff started kicking potato sacks to see if maybe they were hiding.
The sheriff kicked the bag with the red head in it and she yelped “Bark Bark” so they thought it was a dog. He kicked another sack, this one with the brunette in it, and she said “Meow Meow” so they thought it was a cat. Finally, just as the sheriff was about to give up – he kicked one last bag, with the blonde inside, and heard “POTATO!”
