Julie returns to the houseguests to tell them about the food challenge. So far, they have just PB&J, but they can win groceries in the challenge. She sends them out to the basketball court, where they discover three big trees; each has two big birdlike nests in it. The way this works is that they each get a shopping bag, and they grab all the groceries they want from the big table in the yard. Then they climb up in the nests with their shopping bags. Each nest has to be boy-girl. The shopping is uneventful, highlighted by Danielle's continuing admonitions to "get the meat." Man, if I had a nickel for every time I've heard that on this show, I could quit my job and watch the live feeds. They climb up obediently into the trees; the pairs are Marcellas-Danielle, Gerry-Amy, Josh-Lisa, Jason-Lori, Eric-Chiara, and Roddy-Tonya. Just as time expires and they all settle in, Lori emphatically yells, "TWEET TWEET!," which is pretty cute, actually. Julie now explains the weird twisty thing they've introduced this year to try to screw with the dynamics. Because the dynamics are normally so healthy. Anyway, the deal is that whichever pair is last to leave its nest becomes essentially a team inside the house, and that pair wins three thousand dollars for every week they both stick around, so they can split a maximum of $30,000. The general rules of tree-sitting are that they can't go inside for bathroom breaks, they can't sleep, and they have to hang on to their bags and all the groceries they've carried up into the tree with them. So it's just you and your food and whatever sorry person you climbed up there with.
Tree stamina hijnks follow. There's a lot of talk about the possibility of needing to pee. Feet begin to fall asleep. The nests are just about big enough for two butts, but that's about it, so it's like sitting in a big chair together. Interestingly, several of these pairs make really attractive couples, particularly Roddy and Tonya and Eric and Chiara. Eric and Chiara figure out that the best way to sit is actually face-to-face with your legs around each other. It's pretty friendly, but it does look like the least cramped alternative. They seem to like each other quite a bit, and they definitely experience one of those hey-you're-cute, hey-you're-cute-too moments that don't really mean a hell of a lot but...gosh, they're nice. Lisa and Josh are sitting similarly, but they're not having the same friendly experience. They're pretending to be having one, but in reality, they're sizing each other up like the operators they are. He thinks she's hot. He thinks he's hot. She thinks he thinks she's hot. He does. He thinks she thinks he's hot. She doesn't. (Miss Alli's Mom: "This guy gives me the creeps.")
