Natalie and Nadiya are trying to get their diver to hurry up and get them to the building without stopping at McDonald's like he wants to. He assures them he knows where they're going. "I taxi thritty-seven years!" he announces in a heavy accent. One of the twins insists, "Boss, boss, no McDonald's. They're too fat." They all have a good laugh about that. And perhaps they've helped their driver live another thritty-seven months.

Trey & Lexi's driver, as well as Jaymes & James's, get them to the Hotel National, where they quickly find the Petrovsky Room. Inside, a military band is playing an up-tempo number while all manner of rapid, highly gymnastic dancing goes on, courtesy of some extremely energetic men and women in uniform. They get changed into uniforms of their own -- though not without a shot of briefly shirtless Trey -- and go out into the ballroom where the lessons take place. Each team picks an instructor. We find out now -- a little belatedly, if you ask me -- that James sprained his ankle way back in Shanghai and it's been getting worse, but now they'll just have to do that dance, which, given that it includes such ankle-intensive moves as kicking alternate feet from a low squat, is especially tough on James's ankle. Soon the pain has him sweating so freely he looks like an oiled-up Chippendale. "We've got a problem," Jaymes says. Good thing you have another Detour option to go to then, right?

And coming back from ads, they've decided that James is in too much pain to spend any more time trying to learn the dance, so they're probably better off... going into the ballroom and attempting it instead. Chippendale logic, I guess. James can't pull off all the coffee grinders at the end, so they fail. But at least they do than Trey does. Holy God, dude dances like Herman Munster.
