Late night hosts ganged up on the weather:
"It was so cold, the 49ers coach got a concussion when he was hit with a block of Gatorade." — Conan O'Brien
"It's so cold that in Georgia, Honey Boo Boo actually wore shoes. In Maine, lobsters were throwing themselves into boiling pots. In Chicago, people were wearing deep-dish pizzas on their feet." — Craig Ferguson
"With the wind chill it got down to 63 below zero in parts of Montana. At that temperature, if you remove your hat your thoughts will actually freeze inside your brain." — Jimmy Kimmel
And as for the name given to the arctic blast:
"A #PolarVortex sounds like something Mr. Freeze would use to destroy Gotham City... or a new flavor of Powerade." — Jimmy Kimmel
Facebook users had a sense of humor about it, too:
It's as cold as... "A brass toilet in an outhouse in Alaska!"
— WABC New York viewer Jenny Tozzi
"So cold, I saw Superman in a cab."
— ABC7 Chicago viewer Phil Gayden

Even the Associated Press got in on the game:
"The morning weather map for the eastern half of the U.S. looked like an algebra worksheet — lots of small, negative numbers."
— AP reporter Ray Henry
And since we're all stuck inside, here are some that never get old:
It's so cold that...
"...hitchhikers are holding up pictures of thumbs."
"...the optician is giving away free ice scrapers with every new pair of eyeglasses."
"...pickpockets are sticking their hands in strangers' pockets just to keep them warm."
"...I chipped a tooth on my soup!"
"...if you want to hear what someone is saying, you have to grab a handful of sentences and take them in by the fire."
