'Dancing With the Stars' recap: Period Pieces

Aaron and Karina's '90s samba (I am cracking up just typing that, by the way) was another clearly orchestrated matchup between Star and Star's own genre. Karina informed us that ''Aaron had a hit song in the '90s'' — and judging by the pic they showed as she said that, this occurred when he was about 5. After Karina reluctantly agreed to allow Aaron's ''rodeo'' step and more of his best career moves into the dance (my notes at the time: ''ARE YOU SURE YOU WANT TO DO THAT?'') they stepped out and really sold it, according to the judges. Wait, how is this '90s? She has leg warmers. He looks like a bee. Oh, I get it, together they are the tragic/awesome little girl from the ''No Rain'' video. But weren't leg warmers popular in the '80s instead of the '90s (or the 2000s, if you're Edyta)? Oh well, forget it. ''I'm still getting over a sickness so I almost threw up.'' Overshare of the Night!

Donny Osmond and Kym Johnson: 50/60 I'm somewhat shocked that Donny's at the bottom of THE JUDGES' LEADERBOARD this week, but something tells me he'll be safe, and that something is...a very special dance studio heart-to-heart with Kym, featuring careful camera angles, dramatic lean-ins, and a slimming all-black outfit, about how he's going to ''reset'' his view of the competition. Donny's performance value and Kym's gorgeous lavender gown provided wow factor for their Viennese waltz, which included a pretty substantial ''steering the female's head in order to guide her entire body'' sequence. Those always amuse me. After the waltz, the crowd went wild, except for Sabrina and her sidekick, who were too cool to stand up. Donny made the connection between Bruno's ''airy fairy'' quip from a few weeks ago and DANCMSTR's ''arty farty'' from last night — which was pretty astute and quick of him, I thought, unless it was all scripted. Backstage, Samantha accused Donny of ''stealing lines from Tom'' when Tom had actually not been involved in the discussion at all. Does Sam not have audio back there or does she not know which one is Tom?

I have never laughed more heartily at a Dancing With the Stars performance than I did at Donny and Kym's '80s paso doble. Honestly, usually I don't laugh at all. The dances are either lovely and impressive or just kind of boring. This one was a revelation in bad hair, awful music, terrible horrible no-good very bad silver trousers, misguided Bruno one-liners (''That had more camp in it than a drag queens convention''; ''It was Donny doing Marie doing Donny...'') and Kym's faux-seriousness. Whoa, smoke machine! Donny wielding a trash bag as a cape! All 10,000 lights in the Rectagon blinking at random in the style of popular 1980s toy Simon! It was all too much, and I loved it.

Excited for DanceCenter tomorrow? Kenny Mayne...makin' some copies...in his boxers. Talk about last night's performances in the comments, DANCMSTRs, and nominate your own Hidden Gems of the Week. If you don't, I'll be forced to make tomorrow's gem the highly enthusiastic lady in charge of chimes in the Harold Wheeler Ensemble. See you tomorrow!
