With happy homecoming times over, Sunshine and O'Neal's family have a surprise for them in the living room. Oh, and everyone else has a surprise package as well. This can't be good. The box is huge, and wooden, and has the Biggest Loser logo on it. Have they finally made Bob and Jillian robots? Finally, a good use for modern technology! The contestants pry open their boxes and find a metric ton of Styrofoam peanuts surrounding an exercise bike. O'Neal is not a fan of exercise bikes, in part because his poor performance on one got him sent home on the first episode.

The smarter contestants quickly realize that this is probably not simply a gift, but also a challenge. They unwrap a smaller box, which is filled with cupcakes. Little cupcakes, of all colors, shapes, and sizes. Everyone acts like it's the most disgusting thing they've ever seen, except for Stephanie who has a sweet tooth and is thus my people. The package also contains a DVD. It's Sami, who reminds them that on the first day of the competition teams had to bike 26.2 miles -- marathon distance. This week, the remaining contestants will have to bike that distance solo. Everyone's all, "Whatchu talkin' 'bout, Sami?" Furthermore, they have to bike in front of the same crowd of family and friends who witnessed their public weigh-in before they came to campus. The prize for this challenge is $2,500. No, wait, it's $5,000. NO! Wait! It's $10,000. The contestants all want some cash to buy new wardrobes for their skinny selves.

But wait! Remember the cupcakes? They're part of a temptation challenge. Each cupcake contains 100 calories, and for each cupcake that a contestant eats, he or she can add five minutes to another player's time. Evil. O'Neal is not medically cleared to participate in the challenge or the temptation. I think he's secretly pretty psyched about that.
