A redhead, a brunette and a blonde all escape from a prison together.
They run into the nearby woods and all climb up seperate trees.
When the police find the redheads tree and ask who is up there, the redhead chirps like a bird.
Then the police go to the brunette's tree.
When they ask who is up there, the brunette makes chipmunk noises.
Finally, when the police go to the blonde's tree and ask who is up there, the blonde goes,"MOOOOOOOOOO!"
