Three Macho Eskimos were arguing about who had the coldest igloo. So they decided to check each one of their igloos, in turn.
Sure he’d win, the first eskimo pulled back his polar-bearskin blanket, and revealed that his bed was made of ice.
“Nah, mine’s colder,” exclaimed the second Eskimo. And when they reached his igloo, it was snowing inside.
“Pretty cold,” conceded the third Eskimo, “but I’ve got you beat.”
He led the way to his igloo, where he pulled back the bedcovers to reveal a brown spot on the bed. Chipping it off with an ice pick, he tossed it into the fire, and after several minutes they heard a noise, like someone passing gas.
In response to the puzzled glances of the other two Eskimos, he exclaimed with a smile, “My igloo is so cold, that even my farts are frozen!”
