This week's weigh-in is at the American Airlines Center, which sounds to the uninitiated like some kind of museum dedicated to how awesome American Airlines is but actually turns out to be a large sports and concert arena. Unfortunately, Sami, Jillian, Bob, and the Losers don't get to go inside and it's like 34 degrees out. On giant monitors, there's a quick montage of the season thus far, which impresses even Jillian. They're all in full winter gear, which of course each Loser will need to remove for his or her weigh-in. Do goose bumps add weight? Sami recaps the week and opens the floor to comments. Sam talks about how he didn't realize until this week the measure of the whole TBL phenomenon and the size of its fan base. Yes, show, we get it, everyone loves you. Sami brings it back to the task at hand, namely the looming yellow line that she explains to first-time viewers (which, yes, in case you haven't figured it out yet, does include me). Koli, with his immunity, is getting weighed in first, and he strips to his shorts and t-shirt. Sami reminds him he started at 403. Last week he was at 260, and now he's at...259, a one-pound difference. Yikes, good thing he has immunity, right? Everyone's stunned, Koli most of all. "I was expecting, like, a five," he says. "Go get warm," Sami tells him. Well, that isn't going to help.
