An Eskimo man awoke one day with the urge to go hunting for seal. After he had prepared his gear for his journey, he set out over the frozen ice to his favorite hunting spot.
About halfway there, his snowmobile started to run badly and make grinding noises. So the hunter decided to turn around and head back to his village. And, in fact, just as he pulled up to the local mechanic, his snowmobile died.
He went inside and spoke with the mechanic, who agreed to take a look and see what the problem was. The mechanic followed the Eskimo outside to the snowmobile, raised the hood and began to examine the engine.
After a few minutes, the mechanic looked up at the hunter and said, I think that you've blown a seal. No, answered the hunter, those are just icicles on my mustache.
