Big Brother's Cody and Zach Lose Their $*& in This Celebrity Fear Factor Exclusive

Contestants from both Survivor and Big Brother will go head-to-head in this week's Celebrity Fear Factor to see who's tougher, and TV Guide has an exclusive sneak peek at the fierce competition. The video, which will probably be the best thing you see today, features Big Brother 16's Cody Calafiore and Zach Rance locked in glass containers filled with roaches, frogs, crabs and snakes. Yikes!

Even if you haven't competed on a reality competition series, you'll probably relate to Cody who is understandably freaked out by the creepy crawlers. Check out the funny (and deeply gross) video above for hit one-liners such as "holy crap!" and "Oh my God, it's moving!"

The thrilling episode will feature Big Brother 13 winner Rachel Reilly and Big Brother 12 and 13 alum Brendon Villegas alongside Calafiore and Rance competing against Survivor: Cambodia's Abi-Maria Gomes, Survivor: Worlds Apart and Survivor: Game Changers's Sierra Dawn Thomas, and Caleb Reynolds who competed on Big Brother 16, Survivor: Kaôh Rong and Survivor: Game Changers.

Celebrity Fear Factor airs Tuesdays at 10/9c on MTV.
