One year ago Thursday, Olaf almost melted, Elsa built an ice palace, Kristoff introduced us to his rocky family, and Anna delivered the most deserving smackdown this side of the Southern Isles.

"Frozen" came to theaters on Nov. 27, 2013, the day before Thanksgiving, although some parents may not be thankful for the mania that followed. Here's a look at the incredible icy phenomenon.

Trick or treat, there are a dozen Elsas at the door

You probably gave a Snickers bar to royalty this year. Queen Elsa of Arendelle was by far the most popular costume for young girls this Halloween. Talk-show host Jimmy Kimmel dubbed the holiday "Elsaween," and offered up this humorous video showing that not all Elsas are female, or even human.

Jorn Tromolto announces Adele Dazeem

It was a golden night for "Frozen" at the Oscars — the film won for best animated feature and best original song, for "Let It Go," which was sung live on the show by Broadway star Idina Menzel, who voiced Elsa. But according to an introduction by John Travolta, it wasn't Menzel at all, but "Adela Dazeem." Or "Adela Nazeem." Or some other construction of syllables that made zero sense. Of course the name jokes soon flew fast and furious, with the Slate Adele Dazeem Name Generator the best of the bunch. Travolta eventually apologized, and Menzel graciously "let it go."

Do you want to be my boyfriend?

Not only did the movie become a hit, but the "Frozen" soundtrack did too, going triple-platinum. And then came the parodies. "Let It Go" was, of course, a favorite teasing target, from "Here I Go (Despair of an Alto)" (adult language warning) to a med student's despair in "I Don't Know" to one dad's anguished cry for it all to stop in "A Frozen Father." Other songs came in for their share of gibes too. A special favorite was "Do You Want to Build a Snowman?" which was twisted into "Do You Want to Be My Boyfriend?","Do You Want to Get a Beer, Man?", "Will You Help Me Hide a Body?" and others.

Marines and more

Not every viral video of a "Frozen" song was a parody. Some were just awesome. In one, a group of Marines sing along heartily to Elsa's big number, and go entertainingly nuts when she lets down her hair. In another, the "Frozen" characters boogie down with Michael Jackson's "Thriller" dance. And in our favorite, Idina/Adela Menzel/Dazeem joins Jimmy Fallon and the Roots to sing "Let It Go" while accompanied by children's instruments. Who knew the Oscar-winning tune was just missing a triangle, bongos and xylophone to reach the next level of awesome?
