One of the highlights of Survivor 40 is Tony Vlachos. He provides the most hysterical sidebars and keeps fans laughing every week. Let’s take a look at his most recent spy-shack and why fans ...

'Survivor' star Boo Bernis made the first spy shack in 'Fiji.' Tony Vlachos has since elevated it to a bunker and nest in 'Winners at War.' ...

And Tony’s own alliance members are starting to doubt him. Tony builds himself a spy shack near the water well, and eavesdrops as Jefra tells Trish that she doesn’t trust him anymore.

Survivor recap: The Spy Who Shacked Me Tony's scheming doesn't seem to rattle anyone in his alliance except for Jefra, who must make a life-altering decision over ribs.

HitFix’s Daniel Fienberg recaps the Wednesday, April 23 episode of Survivor: Cagayan, titled Sitting in My Spy Shack.

Whether he was handing a fake idol clue to Jeremiah, building his spy shack, or turning Sarah against Cliff, at every moment Tony was both advancing his game and having fun.

But in a season full of returning players bringing their A-game, Ciera Eastin and Tony Vlachos got the early boot, after their tribe, Mana, lost both immunity challenges.

Next week, Tony takes his game to the next level -- really. He's moved on from the "Spy Shack" to the "Spy Nest," and Sarah is "absolutely infuriated." Survivor airs Wednesdays at 8 p.m. ET/PT on CBS.
