Brandon and Janette did a foxtrot that the judges adored, while Jonathan and Karla did a Tony Meredith cha-cha that the judges liked. So who's in trouble? Karla and Jonathan. Brandon and Janette shake their bootys (booties?) as they shimmy off stage.

So while the dancers get ready, Cat welcomes a couple of special guests to the stage: Miriam Larici and Leonardo Barrionuevo. They're dancing a tango. Miriam's kicks look like they can slice the very air. Leonardo's leg twists whip around like snapped elastic bands. They're really good, and the piece finishes with him lifting her up onto his shoulders and spinning around, and then spins her separately around his shoulders and his head.

And now the dancers are dancing for their lives. First up: one night with Paris, who pirouettes and leaps as much as thirty seconds will allow her. Next up: Tony, with some energetic hip-hop that's a little cartoonish. Asuka's cames next with some kind of Latin ... burlesque? A lot of toe-tapping and kicking. Vitolio comes out shirtless. Seems kinda like pandering, but if I were built like that, I'd probably go to work shirtless too.

After the commercial break, Karla leaps and sticks her legs up really high in the air, some kind of mixture of sedation and energy. Jonathan flips and cartwheels like a circus performer before going into some Latin shimmy and another flip. Cat sends the judges backstage to deliberate. "We'll go 'tweet' back there!" says Nigel. Hee!

Luckily for them, this means they get to miss Sean Kingston, who Cat tells me has the hit single of the summer, which is, near as I can tell, Tubby Guy in Red Leather Grunting Into a Microphone. I can see why this is so popular! Kingston's got some great choreography, like the time where he orders people to put their hands up, and then the other time where he puts his own hands up. The commercial break can't come fast enough. Couldn't they have lined up some more dancers? Sean can barely walk across the stage.
