Joanna and Derek have the lambada this week. Derek jokes that the dance has "a lot of grinding and a lot of thrusting," take a beat and then, "I have the best job in America." He really is putting his everything all over Joanna in rehearsals. They are trying to up the difficulty of their routine to get their first 10. And then they go and volunteer with an animal organization, which I am all for, but you know... filler. Derek takes off his shirt before starting the dance, and the ladies squeal. I like their routine a lot more than Aaron and Karina's, for a few reasons. First, there seems to be actual dancing involved by both partners. Second, it's steamy but it feels like it's between two adults, whereas Aaron still looks like a kid to me. And third, it's just exciting to watch, thanks to Derek's choreography. And it is really hot.

Len jokes that he already knows what he wants for the encore, since Joanna started the routine feeling up on Len. He compliments Derek's choreography, although he felt it got repetitive. Bruno thought it was like "when animals get physical." Carrie Ann hopes that the children were in bed, and Tom quips, "I bet some of the adults are now." Tom! Dirty! Anyway, Carrie Ann concludes that it was "fueled by the crotch area" which is how it should be. Scores: Carrie Ann 9, Len 8, and Bruno 9.

Donny went crazy last week and made out with Bruno, and then in rehearsal, Kym explains what Bruno meant by "airy fairy arms." They have the Charleston this week. Donny gets frustrated when he misses steps. Like he falls on the ground and has a temper tantrum. How old is he? Anyway, his routine has a lot of energy, although at times Donny's facial expressions border on creepy for me. And also, he needs to work on his posture, because his shoulders tend to roll forward like a boxer's do. But his footwork is really good, and you can't deny that he's quite the performer.

Bruno thought Donny was a showman in his element, but his feet need to be sharper. Carrie Ann thinks Donny and Kym move well as a team, but she did notice that Donny stumbled a bit at one point. Len has nothing but praise. Do you think the judges got in trouble for being too mean or something? Because I can't believe no one mentioned his posture. Scores: Carrie Ann 8, Len 8, and Bruno 8. I seriously can't get over how overscored Melissa and Mark were.
