A blonde is…

A blonde, a brunette, and a redhead are running from the police. They run into an old barn and hide in potato sacks. The officer chasing them walks into the barn looking for them. He kicks the first sack with the redhead inside and the redhead says, „Woof woof!“ The cop thinks it’s a dog, so he walks to the next one. He kicks the second bag with the brunette, and she says, „Meow meow!“ The cop believes it’s a cat and moves on. He kicks the third bag with the blonde, and the blonde yells, „Potato potato!“
