Shawn's disappointed in their scores from the prior week and Derek notices something's wrong with Shawn during rehearsal. Apparently, during their rehearsal last week for the group dance, she was goofing around with Serena and hurt her knee. She's crying about the injury and Derek interview that they'll have to adjust some of the moves to accommodate it.

So this is a country cha cha to a song about tractors being a turn-on. That is not a sentence I ever thought I'd type. Shawn's solo has a couple of moves that look straight out of a strip club, with splits and writhing around on the floor.

Bruno tells her to forget about the tractor -- she's the sexy one. He likes the fusion of the country two-step and the cha cha cha. Carrie Ann agrees with him and compliments Shawn on how she articulates every move. But then she didn't love the solo. Len thought the choreography was fantastic, the movement was brilliant, but then tells Derek there was too much frippery and too many gimmicks. He doesn't want tractors and cows and whatnot.

Scores: Carrie Ann: 9.5; Len: 8.5; Bruno: 10

Kirstie Alley & Maksim Chmerkovskiy

Kirstie talks about how the other couples seem to look like it's a cakewalk. They have the rumba this week, which Kirstie thinks should be easier for her. Kirstie's having a hard time in rehearsals, with a lack of energy and stamina.

And praise be, Kirstie's wearing more than a bedsheet. See? It's possible to dance the rumba in a real dress. well, maybe not if you're Edyta. I miss Edyta. There's a LOT of dry ice on the floor, so who knows how her footwork is.

Carrie Ann calls her the "queen of sexy" and that every movement was gorgeous. Len thought she coped well with a difficult dance and had good arm movements, but she would have liked more hip movement. He liked it, but not that much. Bruno moves a lot, which I think means he liked it.

Scores: Carrie Ann: 9.5; Len: 8.5; Bruno: 9.5

They REALLY like Kirstie. I'm not sure I'd have scored that better than Kelly & Val.

Apolo Anton Ohno & Karina Smirnoff

Apolo admits he and Karina had a fight before their dance last week and that could account for their lack of chemistry in their dance. Their routine is about a woman suffering cancer and the loved one who's comforting her. This is the dance where Apolo is supposed to be showing his vulnerability.

So this is a Viennese waltz and it's definitely pretty, but I'm not sure I'm getting vulnerability out of it. But then again, see above re: cold black heart.

Len says it was light and had great musicality, "two people in harmony with each other and the music." Bruno calls it graceful and fluid and weightless. Carrie Ann says it was poetry of emotion and mesmerizing.

Carrie Ann makes the point that dance without emotion is "movement for movement's sake." Apparently that's what I like.

Scores: Carrie Ann: 10; Len: 10; Bruno: 10

Emmitt Smith & Cheryl Burke

They're going to be dancing to "Islands in the Stream" and Emmitt's nervous about having to do a solo. His exact reaction is "What the front door?" He's adorable.

So here's their foxtrot -- it starts with them on a porch swing (which, why no "Just a Swingin'" tonight?) wearing cowboy hats. The hats get tossed off pretty quickly, which is kind of a shame because Emmitt looked very cute in his.

The routine ends with Emmitt doing this thing where he has his hands on either side of Cheryl's head and they're doing these rolls? I'm not sure what it's supposed to look like, but it actually looks more like Frankenstein's monster approximating romance. "Guuurl. Gurrl. Gurrrl look pretty." And then it's Emmitt's solo and it's bizarre -- karate kicks, rump shaking, and a few other things. He should've just gone Gangnam style.
