Scores: Carrie Ann: 9; Len: 9.5; Bruno: 9.5

Melissa Rycroft &  Tony DovolaniQuickstep

Oooh, Tony's in a sailor suit. I might've let out a "Well, helloooooo Sailor." They're dancing to "Boogie Woogie Bugle Boy" which is a proper quickstep song.  It's a fun, fast routine, with a lot of energy and pep. Tony is so PSYCHED this season. It's a great thing to see.

Len said it was "quick with a lot of steps" and Tom chuckles, "Thanks for breaking it down for us." Bruno says it was like watching Anne Miller and Gene Kelly in "On the Town."  I wonder if Melissa has ever seen these wonderful classic dancers Bruno keeps comparing her to. (Previously it was Cyd Charisse.)

And now it's time for the "Trio Dances." But first Tom gives us a rundown of the leaderboard. Apparently tonight's scores will be combined with last week's judges scores and all the fan votes to produce the double elimination tomorrow night.

For the trio dance, each couple will work with an already eliminated pro to do a three-person dance. As Tom is trying to explain the concept, Mark, Shawn and Derek ride behind him on tricycles while dressed like cavemen, naturally.

Shawn & Derek with Mark BallasSamba

They've decided to go "tribal" and we see Shawn standing in front of the two of them (all three facing forward) and then Derek and Mark execute some "Magic Mike" worthy pelvic thrusts. When they stop Derek chides Shawn that she can't just stand there and look "scared and confused."  Honey, if I saw the two of them behind me in the mirror doing those pelvic thrusts I'd absolutely be scared and confused.

Derek says they're going to mix samba elements with "tribal elements." I'm pretty sure Len's not going to be a fan. But they're not worried about that and they totally play to the audience.

It's certainly different than a lot of what we've seen on DWTS. I really liked it but I'm not sure how "samba" it was.

Len says "if I was sitting in the audience I'd be cheering along. But I'm not; I'm sitting up here and I've got to judge a samba." Len then calls them "self-indulgent" and criticizes the lack of samba content. He adds that it's a critical week and says "Shawn, if you go home tomorrow, don't blame me, blame those two [indicating Derek and Mark]."

Bruno calls them "naughty" and says "as a piece of dance as art it was absolutely fantastic" but even he has to admit that it wasn't really a samba. Carrie Ann disagrees with both of them, saying that they had to take risks and what samba they did do was executed perfectly. And then Derek and Mark do these really gross pelvic thrust moves at the judges and it's really immature and awful and they're both "On My List" now.

Derek claims that they went risky with the routine for the fans at home because they audience is bored of seeing the same old dances over and over. NO, WE'RE NOT. Do you think us old people make NCIS the number one watched show on TV because it's DIFFERENT EVERY WEEK? Ditto: the CSI franchise, The Mentalist, Castle, The Big Bang Theory, Two and a Half Men, etc. Leave innovation to the cable channels - we want familiarity from our network offerings.

Scores: Carrie Ann: 10; Len: 7; Bruno: 9

Way to stick with your principles, Len. Bruno should have done the same. Otherwise you're just telling Derek he can keep getting away with this. Especially after you judges didn't ding them overmuch for their "Screw your 'no lifts' rule" routine earlier in the season.

Karina & Apolo with Sasha FarberJive

Apolo explains that they chose another male dancer so that he'd have a pro to emulate during the routine. Smart thinking, especially if Sasha doesn't show him up. During rehearsal, they're doing this crazy double leap thing over and under Karina and it looks like a neck injury waiting to happen.

They're dancing to "Greased Lightning" and Karina is wearing a red spandex bodysuit. It's something only someone that looks like her can pull off. And hey! There's the leap from rehearsal and they mostly nail it. The dancer that went through her legs (Apolo, I think) didn't go through as far and fast as he maybe should have.

Bruno says they took a "huge, huge risk" because all the way through Apolo was mirroring a pro, but he conquered it. Len says it was fast, sharp, tight, and together and that's what you want from a jive.
