Drunken cameramen swoop across the water and land at the next immunity challenge. It's set out in the water, and Jeff welcomes the five remaining stragglers. He takes the Supreme Cutlass from Darrah. "I need this back...back to back it's been on your...back," he says. Something about Darrah certainly does make Jeff think about backs. The immunity challenge, as it turns out, is one of those that's very hard to explain without using schematic diagrams and scale models, but I'll do my best. Basically, you have to use your canteen to put water into a narrow tube so that a float rises to the top. The float has a key attached, and the key unlocks a plank that's locked in a vertical position, and when you unlock it, you can drop it down and walk across it to the next one. You do this for a whole series of planks, until you reach a flag at the end of the course. You take the flag and walk back across all the planks to the starting line, and then you are the big winner.

The contestants all take their spots at the beginning of the course. "Survivors ready...go!" The challenge starts with non-incredibly non-dramatic canteen-filling, but fortunately it picks up a little after that. Darrah only has to put one canteen of water into the tube, as it turns out, because she's got such little hands and arms (especially right now) that she can reach far down into the tube to get the key out. Darrah, therefore, lets the first plank down, while everyone else goes back for more water. Basically, the way this goes is that everyone is fairly close throughout, except for Sandra, who falls somewhat behind, and Lill, who eventually has trouble with one of her planks, which gets stuck. In the end, though, Darrah's small hands and her good balance and agility seem to be the key factors in getting her to the end before everybody else, so the peppy mortician is taking the Supreme Cutlass for the third time in a row. Incidentally, there were those who thought it was unfair that Darrah's hands were smaller, so that she could reach down farther in the tube, but considering all the challenges they've done on this show where it's an advantage to be built like Bluto, it seems to me that it's entirely fair that there might be one now and then that favors smaller bodies. Jon and Burton seethe. Jeff explains that Darrah will be safe at the next tribal council, but that everybody else is on the block. Sandra smiles. She's pretty sure that's Burton's ass she hears crackling in the growing fire.
