An Irishman, Englishman and a Scotsman are running from the police. They see a barn on the horizon and quickly run to hide there.
Inside are 3 big baskets, one full of cats, one full of dogs and another full of potatoes.
The Englishman quickly jumps in the dog basket and closes the lid, the scotsman then jumps in the cat basket and closes the lid, leaving the Irishman to scramble into the potato basket.
The police surround the barn and the chief plod enters the barn with his oficers.
He walks over to the first basket and kicks it. 'Woof' calls the Englishman, and the chief plod realises it's just dogs moves onto the next basket and kicks it. 'Meow' calls the Scotsman, and realiing it's full of cats the chief moves to the last basket and kicks that, and the Irishman shouts "Potatoes."
