Yay, Hairspray director Adam Shankman is back as the guest judge on tonight's So You Think You Can Dance. He was super fun last time.

Nigel points out that it is the highest-grossing opening "of all time" for a musical. Then we learn that each couple will dance twice this evening. (Hopefully not with a saccharine solo repeated 10 times over like last week!)

Danny and Sara are assigned as partners and draw Argentine tango (with Alex de Silva) and hip-hop. They start with the tango, to a remix of "Whatever Lola Wants." It's very stylized and sexy -- though it's a little odd because Dannys dressed to the nines in a suit and Sara is wearing thigh-high boots, a sparkly bra top and hot pants. It's like they got costumed for separate performances. But they do a tremendous job. Adam says he thought they would be a total mismatch, but "this was unbeepin real and so beepin hot." (He really did say beep.) He says Danny has "the best center I've seen in my life" and that he's the best male dancer ever on the show. Mary praises Dannys turns and talks a lot more and finally says, "I loved it." Nigel makes reference do it being a takeoff on the song's appearance in Damn Yankee, so maybe the outfits were an artistic reference I didn't get.

Dominic and Lauren are partners now, and they get krump (with Lil C) and rumba. Krump is first, and it's a really engaging routine with some interesting twists. They do a whole pretzel thing at one point, and at another, Dominic slides across the floor toward Lauren and she runs across his back. Adam is rendered almost speechless. For a moment. He says it was hot, though he isn't sure it showed off their strongest potential as dancers. Mary says the first part had a ton of energy but that it started to die off toward the end. Nigel says krumping is way tougher than hip-hop and that he didn't really get that differentiation in this routine. He also says he didn't like the music. He asks Lauren if she was meant to fall during the running-over-Dominic move, and she doesn't seem to want to admit it, but finally she does say she fell and was covering it.

Lacey and Neil will be dancing together for the first time. They draw Latin jazz (with Maria Torres) and contemporary. The first is Latin jazz, and in the interview footage, they are both worried about this lift called a "crunch," but when they're performing, they totally pull it off. It's a fun routine, and they seem to work well together. (For the record, Neil performs with no shirt.) Adam says that if Neil gets a ton of votes this week, he thinks the show is going to turn into So You Think You Can Dance in the Nude. Well, if anyone would go for that, Fox would. He says the great news is they are beautiful dancers. He tells Lacey that she needs to break the bad habit of staring outward and to look more toward her partner. Mary says the chemistry isn't there for her at all. She says it was forced chemistry. But she says there was some brilliant dancing inside, too. Adam starts talking again and agrees that he wouldn't think they wanted to tear each other apart, but that the dancing was still beautiful. Nigel finally gets a word in edgewise and says that he loved the music and the routine and that he didn't love either of their performances. He says they both danced too high.

Sabra and Pasha are paired together and they get Broadway (with Tyce DiOrio) and quick step. Their Broadway routine is from The Wild Party. It's fast and busy and tiring and fun and very Broadway. Adam says he didn't think he was going to like it because this kind of number usually needs a giant chorus, but he got really drawn in and really got surprised. He adds that Pasha was good, but the bad news for him was that Sabra was "a revelation." Mary says Sabra is always a revelation, and, "Pasha, tonight you were for me too. ... I just loved all of it!" Then she gives the patented Mary scream. Nigel says Tyce's choreography forces dancers to perform (character-wise) and that they showed why they are in the Top 8.

Sara and Danny are back for their second performance of the evening, a hip-hop routine with Shane Sparks. Danny says he is worried because Shane didn't want him in the Top 20. Shane says he thinks Danny changed his mind. They dance to "Push It," and there is an appropriate amount of pelvic thrusting given the song title, and a bunch of great moves, some of them amusing, too. Adam asks what they did to the wardrobe department to get them so angry (yes, I failed to mention their totally 80s madness outfits). Nigel says they look "not so much ghetto, more Sesame Street." Adam says they are the most versatile couple and could do anything. Mary says the dancing didn't do it for her because it wasn't hard-hitting enough. She also says they looked "too cute for this hip-hop." Nigel says they both went for it, but they didn't achieve it together.

Lauren and Dominic's second dance is the rumba with Tony Meredith. Their dance is to "Ain't No Sunshine," and it is very slow and sexy. I don't love Lauren, but she is getting better. Adam says the chaperones better keep their eye on these two after the show. He says he liked it, but it didn't feel like a rumba to him because there was a lot of posing. Mary agrees that this is a different rumba, but it had great lines. She did say that in the Latin dancing steps, they were a little off. Nigel says wardrobe made these two look wonderful. He adds that Dominic stayed in style and character with his face last year (unlike last week when he called him almost a caricature). He says that the choreographers have been making the dancers look good and playing to their strengths, and next week, the choreographers will be doing what they do best, and creating more of a challenge for the dancers.

Lacey and Neil are next with a Mia Michaels contemporary routine. Michaels says this dance is about a reunion in heaven between her and her father, who passed away two years ago. No pressure on the dancers to get this one right! It's very lovely and sweet. Adam thanks Mia for bringing something so personal and emotional out into the public. He says he is in love with what they just did, that they were acting in this whole other world rather than dancing and that "this will be going down as one of the best dance performances on television ever." Mary can't talk because she's crying and she makes a heart shape with her hands. Nigel says she is going through a tough time in her personal life, and she seems to break down more. He says they danced with emotion rather than technique and that it was one of the most beautiful things he's seen ever.

Then, the last dance of the night, Sabra and Pasha with a Tony Meredith quick step. It's quick. And full of steps. It's not that it's not good, but I was so distracted by how much my TV hated the stripes on their costumes (it looked like there was a big rip in Pasha's jacket, but it was just the pixels freaking out. Adam: "Awesome, great choreography ... great use of the stage." He also loved the attitude. "You freak me out, you are so good, young lady," he tells Sabra. Mary says that was a very, very difficult routine and that they "tore this up." Nigel says they needed something to cheer them after the emotional routine that preceded it. He says that with both of their routines together, they are the best couple of the night for him.

I feel so indecisive, but I pretty much liked everyone tonight, even the routines the judges were lukewarm about. What did you think?
