Potato.

  Ok, so there's a blonde, a brunette, and a red-head. They were snooping aroung in a farmer's crops one day, when his son saw them. So he picked up his gun and chased them off the property yelling "No trespassers."

 The next day, they came back. The farmer and his son saw them this time, and chased them with gun again. So they ran until they came to a shed. Inside they found three sacks and got in them. The first one was labeled Puppies, so when the farmer and his son opened the shed and kicked the bag, the brunette went "Woof woof." The next one was labeled kittens, so when they kicked it, the red-head went "Meow meow." The last one was labeled Potato, so when they kicked it, the blonde went "Potato Potato, and was shot.
