"the Eskimo" joke

An Eskimo was riding across the tundra on his snowmobile, when it started
sputtering. The Eskimo cruised into town, and stopped at a mechanic's shop.
After five or ten minutes, the mechanic returns, and says, "Look's like you just
blew a seal." To which the Eskimo replied, "No, that's just frost on my
mustache."
