And then, challenge time! We get to see Sami Brady, who makes a pun about taking steps. Get it? Get it? Do ya? The teams are standing in front of a ten-story building, in which the lights have been left on. Each team has a stairwell, and one by one, a team member has to go up the stairs and flip off one of the switches on floors 7 - 10. The first team to flip them all off wins. And what do they win? One member will win immunity. Neil and Ryan have some injuries. Neil's is a foot injury resulting from the hike, and Ryan had some bloodwork come back that shows he might be working too hard. One member of the Red Team has to sit out to even up the numbers, and it's Lezlye.

The teams begin their slow individual ascents, followed by their slow individual descents. Some really tension-filled music plays in the background, but the whole challenge is honestly taking a year. And it's just not that exciting to watch people going up and down stairs. It makes me kind of tired, to boot. With the Blue Team in a slight lead, it's Jerry versus Phil. And Phil seems to be a little bit better at climbing stairs than Jerry. Phil says he's going to win it or die trying. That's a little dramatic, isn't it? Phil turns off the light, but the challenge is all about who crosses the finish line first. Meanwhile, during a commercial break, we learn that seven spoonfuls of sugar are in a can of cola. That is terrifying. The team captains race down the stairs...and Phil wins! It's really close, though. Neil tells us that the Jerry/Phil rivalry is like Ali/Frazier. I think Lilith/Frasier would be fiercer.

The team flips switches to determine randomly who will get immunity. It's not Lezlye, which is fair. She said she didn't want immunity, since she didn't participate in the challenge. Phil doesn't get it either. Cowboy David has some cockamamie symbolic method of doing it, but it works. He's happy, but knows he can't relax, because a girl's gotta work to lose some of the junk in that trunk.

Bob sees his team the next day, and they are downtrodden about their loss. Bob tells them that Phil had something to prove, and didn't want an old man to beat him. He has to wrangle them and motivate them to get back in the gym, and does so by telling them that no team has ever won the first two weigh-ins. Neil says they're ready to make history. A really specific kind of unimportant history, but okay. Kim tells us that the next weigh-in is making her sick to her stomach, I guess because a couple of the folks are not working so hard. Amy realizes she's not giving 100%. She doesn't want to give up, but weight loss feels like a constant battle that's never going to end. Kim engages in some tough love. Actually, it's kind of bitchy love. I mean, what can you expect? She's no Jillian.
