Coldest Igloo

Three Eskimos are sitting around an ice hole fishing when the topic of coldest igloo pops up.

The first Eskimo says, "My igloo is definitely the coldest. I'll show you"

So they all head over to the first Eskimo's igloo where he says, "Watch this."
He gathers up a big wad of spit in his mouth and spits out. When the spit hits the floor all they hear is "plink, plink, plink".
The second Eskimo says, "That's nothing. Let's go to my igloo."

They all head to the second Eskimo's igloo and pile in.
The second Eskimo says, "Watch this."
At this point the second Eskimo pulls down his fur laden pants, whips out his penis and starts pissing in the air. As the piss arcs towards the floor, the Eskimos see the pee start to freeze mid-air in a perfect crystallized arc before a drop even hits the floor and then shatters on the floor.

The third Eskimo chimes in, "Impressive, but you aint seen nothing." He ushers them to his igloo, and when he gets there he starts shuffling through some dirty clothes in a hamper. He pulls out a pair of white underpants and holds it up for the other two Eskimos to inspect. All they could see was that the underpants had a brown streak on the back.

The first two Eskimos look at him puzzled. The first saying, "So, you shit yourself, that doesn't make the your igloo the coldest."

The third Eskimo says, "Hold on, hold on." He goes to a nearby fire and holds the underpants over it.

After a few seconds they hear the underpants let out a huge long fart.
