Hello ... Bones?

Former Seinfeld star Wayne Knight will guest star on the Fox hit later this season, channeling his inner Willy Wonka as a candy magnate in an episode that will include “one of our most revolting body finds ever,” executive producer Stephen Nathan tells EW.

In the episode with Newman Knight, Booth & Co. are in for a sticky situation: “A body is found inside one of the world’s largest chocolate bars. It’s delightfully revolting,” Nathan says.

Sounds like that one might earn a place in the Bones Rotting Carcass Hall of Fame. In other Bones casting news, Arnold Vosloo will play the sniper terrorizing the team in 2011.
