Margie and Luke have finished in 8:05.30, less than twice Phelps' time (by about two seconds, but still). "I just want to get this suit off," Margie says as they read their clue. The Speedo LZR: the most advanced swimsuit you'll ever loathe.

Despite being in first place, the cheerleaders aren't resting on their laurels. Quit the contrary, in fact. "Our luck with taxi drivers is never good. We could leave in first and end up in fourth," Jaime says. That's all true, except the part where they could leave in first.

Tammy and Victor score a three and a four, and then Jen and Kisha make their first attempt at the synchronized dive. There's a wide gap between them, so they rate a pair of twos. They clumsily swim back to the edge, Jen looking like she's in imminent need of rescue at any moment.

"We swam great!" Luke celebrates on the way to the Pit Stop with his mom.

Back at the diving board, Jen wants to let Tammy and Victor go again, because she's not ready for another shot. "This is, like, our twenty-thousandth dive," Victor says as they ascend. I think he's exaggerating, unless he's counting each dive as two. In which case he might not be far off. They get another close one, but at three and four, it's not as good as the one before. "How do we get a five?" Victor asks Tammy in Mandarin. "It's hard," Tammy agrees. So clearly trying to get on the judges' good side by speaking their language couldn't hurt. After watching another demo dive, the sisters make another leap. "What'd we get?" Kisha asks from the edge of the pool, spitting a big foamy loogie into the water. Two and three. Tammy and Victor's turn again, while Jen leans against the wall saying she can't do it. "We're getting better," Victor insists after he and Tammy post another seven-point score. He tells her to decide, and they go back to look at the clue. Meanwhile, Kisha encourages Jen, "You've done stuff harder than this, all right?" Jen is, by this point, actively crying. And Team Family Law decides to make the switch. Kisha tells Jen nobody will let her drown (thanks for ruining the suspense again, some more), and they get back on the boards for another try.

"Go!" yells the swimming coach, and Tammy jumps into the pool feet-first to begin her first lap. Speedo: "Oh, for fuck's sake."

Kisha and Jen make another jump and barely make it to the edge of the pool alive before seeing they got a 2 and a 3, which is pretty generous if you ask me. "We're not gonna get this," Jen says. Over at the lap pool, Victor tries to offer encouragement to both Tammy and himself. Jen is still in tears as Kisha asks what she wants to do. Tammy finishes her first lap (2:31.30). And now Jen is sitting on the floor in he hallway outside the pool area, with her back against the wall, as Kisha crouches in front of her asking what she wants to do. "I want to go home," Jen sobs. Kisha says they've come this far, but Jen isn't hearing it. "Jesus, help her," Kisha murmurs. Obviously, Jesus is not going to appear, or else that probably would have been spoiled in the preview.
