A blonde, brunette and red head escaped from jail. They were being chased by the police. They were running through the streets when they saw an old barn. So they ran in and found three heshin bags. They all jumped in.

The coppers walked in the barn and saw the three heshin bags.
One copper goes to the other "Kick the heshin bags to make sure nothing's in them"

So the copper walks up to the heshin bag with the brunette and kicked it.

The brunette said "Meow Meow" and the coppers thought it was a cat and walked to the next heshin bag.

The copper kicked the second heshin bag with the red head in it.
The red head said "Woof Woof" so the coppers walked to the third heshin bag thinking a dog was in the second one.

The copper kicked the third heshin bag with the blonde in it.
And the blonde said "Potatoes".
