Potatoes

There are three girls who have just robbed a bank and a running from the police, they realize that they will be caught soon. Suddenly the first girl, the brunette sees three empty potato sacks and jumps into one of them, the red head following the brunettes lead jumps into the next one, after the blonde sees what the other two have done she jumps into the third sack.

all that you can see of the girls is their hair peeping out of the sacks.

The police come racing down the street looking for the girls, all they see the potato sacks and the hair, so they kick the brunette thinking quickly she yells out "woof woof" next the police kick the red head so she does the same as the brunette and yells "meow". 

Last but not least they kick the blonde and so thinking that she was being smart calls out "POTATOES!"
