An Eskimo goes on his holidays to Wales. While he's there he hires a car to get about.
He's driving along and the car breaks down, a big cloud of steam coming out from under the bonnet. So he rings a garage.
The mechanic comes out, has a look under the bonnet and says to the Eskimo, "You've blown a seal"
The Eskimo replies "So what? You lot shag sheep"
