|A few of my favorites. Feel free to leave your own cold/colder comments in the comments section.
It's so cold that my Christmas decorations are now permanently affixed to my house.
It's so cold that my runny nose is now a small icicle.
It's so cold that even Mother Nature has been asking for another blanket.
It's colder than an Eskimo's Eskimo pie.
And my personal favorite, although I don't know why...It's colder than a witch's titty
