Meryl and Maks Gave Us Chills and More Dancing 10th Anniversary Moments That Were Perfection

Ten years, 20 seasons, hundreds of routines, tons of happy (and sad) tears, a handful of injuries and thousands of sequins later, it's Dancing with the Stars' big anniversary!

The one-hour special reunited past winners like Meryl Davis and Maks Chmerkovskiy and Tony Dovolani and Melissa Rycroft, showcased fan-favorites like Amy Purdy, and was filled with fun dances, musical performances and more! So let's break down all the moments from the monumental dance party.

VIDEO: How well do Dancing's Derek Hough and Nastia Liukin know each other?

We open with a big number that includes pros like Artem, Maks, Witney,Sharna, reigning champ Alfonso Ribiero, and in the audience I spot Lea Thompson, Lea Remini, Danica McKellar, Corbin Bleu, Jonathan Bennett and more! Soon, Tom Bergeron kicks off the night with holograms (seriously, holograms!) of epic moments like Steve Wozniak worming across the dance floor, Witney and Alfonso doing "the Carlton" and Marie Osmond fainting.

We then see a montage of all the past winners from Kelly Monaco to Alfonso before the performances really kick off. Up first, we're treated to Kelly and Val re-creating their half-naked All-Stars "Surfer Flamenco" dance that was clearly ahead of our Fifty Shades of Grey time. Also, I feel uncomfortable.

Kristi Yamaguchi is up next with Mark dancing to "Uptown Funk" and they're soon joined on stage by Amy, Sasha -- who replaces the injured Derek Hough -- Maria Menounos, Chelsie Kane, Amber Riley and a 4-months pregnant Katherine Jenkins. Full disclosure: I have to Google Katherine Jenkins. FYI she's a classical singer.

Dancing's Derek Hough: injuries are "incredibly frustrating"

Next, a montage of injuries reminds us that this isn't just fun and games, it's intense too. And the tantrums, oh the tantrums. But hey, Maks and Len have kissed and made up! The inspiring segment of clips then reminds us there are pretty amazing people in this world like Amy, J.R. Martinez, Marlee Matlin and this season's contestant Noah Galloway.

It's time for a champion showdown! Alfonso and Witney are still so good and so effortless, and when Tom checks in on his groin injury we learn he's all healed! "When you're hit in the sack, just get a snack," he says. We'll remember that one. Meryl and Maks, my all-time favorite couple, still give me chills with their number to "Heroes (We Could Be)." I still like to pretend they could be a couple.

We're then finally treated to Maks' audition tape, and it's perfect. Never change, Maks, never change.

Melissa and Tony show off their finale samba and in case you already forgot, Melissa is hosting the Perfect 10 tour.

Dancing with the Stars: How did Derek Hough's stand-in do?

Ever want to know the judges' all-time favorite dances are? They're about to tell us! Len Goodman highlights Helio Castroneves and Julianne's Season 5 quickstep, Carrie Ann Inaba names Amy and Derek's moving Season 19 contemporary, Julianne picks Donald Driver and Peta's Season 14 Argentine tango and Bruno Tonioli -- showing off his bare chest -- picks Mel B and Maks' Season 5's Paso Doble. And speaking of Pasos, NFL alums Kurt Warner, Jacoby Jones, Michael Irvin, Donald Driver, Hines Ward, Jerry Rice and Emmett Smith take the stage in gold lamé jackets and absolutely rock it! They should totally do a Dancing with the (NFL) Stars season, right?

The hour flies by and winds down with a musical performance of "Lady Marmalade" from Lil Kim, Amber Riley and Patti LaBelle who bring down the house. A quick montage of past contestants talking about what the show has meant to them and then the special really comes to a close with every alum in the ballroom, all four judges, and even Tom and Erin joining in on a group dance.
