And what does Dan win, you may ask? Sami lifts the cover of the tray to reveal...a giant piece of chocolate cake. Everyone is puzzled. Sami says that the cake is exactly 600 calories. Dan is welcome to do what he wants with it, but Sami's suggestion is that he bring it to the next challenge in one piece. Sami is totally off her meds again.

Back at the house, Dan enjoys some 200-calorie strawberry yogurt as Mark says that a little cake frosting would hit the spot. Dan realizes that he has to keep an eye on his piece if he wants it in tact at the next challenge. He thinks about his cake as a pet. I nibble my cat's nose all the time, so I don't know if that would be a good strategy for me. Roger interviews that if he could take a bite out of Dan's cake he would, because cake is a weakness of his. And he wants some of it. You guys, Roger totally wants Dan's piece. If I were Dan I'd sleep with the lights on. Pride on three!

Dan brings the cake to the gym. This is like when teenagers get egg babies in health class. The ubiquitous presence of the cake is making Bob crazy. So crazy, in fact, that he screams and taunts his team. He wants to push them to such an extreme that they feel like they can't go any farther. Bob really gets under Mark's skin, and breaks his usual laser-like workout focus. Mark kneels on the treadmill and tells Bob he doesn't have any legs left. He has run them into little muscley stumps. Bob tells us that when someone can't go any farther, he'll expect a little more. It makes a person stronger. I think Bob has gone mad. Mark knows that his workouts have to be really intense if he's going to lose enough weight to stay in the game. I know he wants to win the cash, but I personally think he looks great and that he should stop dropping the poundage now. But Bob likes his fellas manorexic, so they continue.
