Two Eskimos were talking about the cold. One said to the other "you don't know what cold is", "my igloo is colder than yours".
So the two of them went into his igloo, and he picked up a pan of water from the fire and threw the water across the igloo, but it froze in mid air. The other Eskimo said his igloo was colder.
They entered the second Eskimos igloo, and he proceeded to pull back the fur covers of his bed, and there lying in the middle of the bed was a little blue blob. The Eskimo picked it up on his shovel and held it over the flames of the fire where it went "Phaaarrrp"!
