Shark Week Walking Dead star kills zombie shark (Josh McDermitt and Michael Cudlitz)

Walking Dead stars Josh McDermitt and Michael Cudlitz dropped by Shark After Dark to lend their expertize on Zombie Sharks, a Shark Week special that examines a phenomenon where sharks enter a catatonic state when flipped upside-down. Predators like octopuses and otters have taken advantage of this to prey on smaller sharks.

The Shark Week mascot, Bob the shark, was zombified but McDermitt and Cudlitz assured him they wouldn’t stab him in the brain. The actors explained they love sharks but not bad puns. Cudlitz bashed his brains in with a rock when he start pitching Shark-themed shows like 2 Broke Gills, Person Finterest and Whale of Fortune.

Later in the show, host Josh Wolf personally tested a chain mail suit used to allow divers to interact with sharks without a cage. Cudlitz repeatedly stabbed him in the chest with a kitchen knife at his insistence.

“By the way, I don’t think I ever envisioned me staring into your eyes saying harder,” Wolf joked.
