Borneo: Sean. "Alphabet Strategy", Super Pole 2000, the sand bowling alley, all easily net him the prize.
Australia: Elisabeth. Ruined Kucha's chances to take back control of the game, when they had the chance to do it twice after Jerri's exit.
Africa: Kim Powers. Her refusal to not vote for Brandon at F8 cost all of Samburu the game.
Marquesas: Zoe. Showed no loyalty to anyone, guaranteeing herself a quick exit after John's demise.
Thailand: Whoever decided it was a good idea to throw the episode 6 immunity challenge.
Amazon: Wow, this is a toughie. Heidi, Roger, Dave, Christy, Matt, Alex and Butch probably all deserve induction. From a game standpoint, Butch was probably the most clueless, so I'll go with him.
Pearl Islands: Burton. Convinces tribe to throw challenge, only for them to vote him out! And then trying to vote out Lill at F5?! Taking Jon on reward?!
All Stars: The Twatwaffle. That one's easy. Voting out all the strong guys on the tribe AND voting out Jerri over Amber? LoL!!!!!
Vanuatu: Lisa. Voted out Mia for no reason whatsoever and soon found herself packing for what else, but loyalty issues.
Palau: Ian. Until Erik's wonderful decision last night, the clear cut #1 dumbest decision of all time.
Guatemala: Stephenie. Completely blew what would have been an easy victory by backstabbing all her allies except Rafe, who she had no chance of beating.
Exile Island: Terry. Voting out Dan, his horrific attempts to flip members of Casaya, and going along with Danielle at F4 after she had already betrayed him earlier.
Cook Islands: Billy. Yes, Candice really does love you!
Fiji: The casters for casting Melissa McCunty and not even thinking to bring an alternate.
China: James. Two idols. Three TC's Doesn't use one. Nuff said.
Micronesia: Is there any question here? :P

At the final 4 (in exile island) Terry really should have just voted out Danielle. Cire was a jury threat, but she wasn't a challenge threat. He would have only had to worry about Aras in the next immunity. I don't know that he could have beat Aras at that challenge, but Cire wouldn't have won it.
