The plot of "100 Clues" sees Shawn invited to a dinner party at a mysterious mansion, Bella Rosa. Since Jules is tied up at work, Shawn invites Gus to attend with him. We had to ask Tim -- do Lassiter and Jules get involved, too? He assures us that they do.

"Because of the hijinks, Lassiter and Jules are called to the house to solve the crime ... or alleged crimes. They are very much involved," says Omundson.

"That was ... [ pauses] we do a lot of surreal things and we have a lot of surreal experiences on our show as actors," he continues. "But you look around at who you get to play with that week [for '100 Clues'] and that was a tour de force cast by our casting department."

"It was just unreal," he continues. "People I grew up watching. Every day was just -- you're a kid in a candy store. When you get to play with people like that on a level like that, there's nothing better."

He also assures viewers that you do not have to be a connoisseur of "Clue" to enjoy the 100th episode.

"I do not think anyone will be disappointed by the 'Clue' episode, whether you've seen the movie or not," says Omundson. "It's a cornucopia of the greatest guest stars. Certainly the greatest group of guest stars we've had in one episode."
