Probst explains the challenge. There are three stages. First, all contestants dig to find a club they will use to break a tile. The first six to do that get to stick their heads in a tub of water and suck up as much water as they can, then crawl under the tub and spit the water out into a tube. The first three people to fill the tube past a line move on to the third and final around, another one of those tricky-looking block puzzles. The first person to solve it wins immunity. The challenge begins. Rob and Grant are the first to get their clubs, smashing the tiles one after the other and sending tile shards all over Probst, who clearly loves it. Ralph and Mike are the next two to finish. David gets fifth place, and Julie gets her club but decides to delay her win slightly by walking over to the other side of the tile to smash it for some reason. Was she trying to hit all the losing contestants with tile shards? Weird.
Grant continues his dominance in the second round, being the first to spit water into his tube. Probst praises his skill and speed. He really seems to enjoy watching men with their mouths full of liquid spitting into tubes. I'm just saying. Like the first round, Grant is the first to move on. Mike gets the second spot, while Julie's tube isn't even half full yet, so there's probably little hope for her. Probst screams at the contestants to "DIG!" which has become his favorite thing to yell during challenges, even when they don't involve any actual digging. Rob's next spit doesn't reach the line, giving David the chance to grab the third spot in the final round. This is great news for David, since it's a puzzle and he's always telling us how good he is at those. Now he can finally prove it! Probst calls go, and puzzle-solving ensues. Mike's block tower looks nearly complete, but he can't seem to figure out where to put the pieces that make up the very top. Meanwhile, Grant suddenly has his puzzle almost entirely completed. David is nowhere close to them. Grant calls Probst over to check out his puzzle, and Probst proclaims him the winner. That means that David, the puzzle expert and lawyer, just got bested by a football player. HAHAHAHA!
Murlonio return to camp. Mike is very disappointed about coming in second again and figures someone from his tribe will be going home tonight, probably him. He says they'll need a miracle, and then thinks he might have found it when he notices that the tribe flagpole moved while they were all at the challenge. He points it out to David, and they start to dig, hoping to find an idol. After a while, Rob notices them and commands his troops to the flagpole to dig, too. David sees them coming and mutters "let's screw with them" to Mike. Phillip sprints up and starts digging around. Andrea is behind him, looking sheepish because she knows how silly this is. "We're just looking for rocks," Mike lies. Rob soon arrives with a bunch of shovels, and the digging begins in earnest as Mike and David observe. David interviews that he and Mike had already realized there was not idol to be found in the sand, who it was fun to watch Rob and the "Mariano crime family syndicate" waste their time and energy digging several feet down for nothing. Mike chuckles in an interview that Rob may be thinking that he or David already managed to dig up and find an idol before he got there. Sure enough, Rob interviews that after an idol ruined his game last time, he can't be too careful about them or too paranoid. So now he's hesitant to tell his tribe to vote for the obvious boot, Mike, because if Mike does have an idol and plays it, it could take Rob out of the game.
