"The coolest one !!" joke

There were three friends Santa, Banta and Jugnu in Shimla. Once, while they were at their local bar, they got to talking about how cold it was outside, and how cold their residences were. They could agree on everything but whose residence was the coldest, so they decided to determine who indeed had the coldest house.
They went to Jugnu's residence, where he said "Watch this!"
Jugnu poured a cup of water into the air. Well, the water froze in mid-air and fell onto the floor solid.
"Not bad", said Santa and Banta.
So they went to Banta's residence, and he said "Watch this!"
Banta took a big breath and exhaled, whereupon his breath froze into a big lump and fell to the floor.
"Wow, that's colder than mine!" said Jugnu.
But Santa exclaimed that his was colder still. So they ended up at Santa's residence.
Santa said "Watch this!"
Santa went into the bedroom, threw back the thick furs, and retrieved one of several small balls of ice there. He took it, put it in a spoon, and held a match under it.
When it heated up enough, it went "FFFAAAARRRRTTT".
