The only thing to fear is guilt itself -- because this 90-minute edition of the gross-out game show is a hoot.

Watch it. Tell no one. Relish in your shame.

Fort McMurray's own Natasha Henstridge joins a lineup that includes Penn and Teller, Gena Lee Nolin and Barry Williams of Brady Bunch fame.

Hard to pinpoint which moments contain the most joy.

Seeing Williams -- who has now appeared on this, Celebrity Boxing and the forthcoming Celebrity Bootcamp -- about to be crushed by a monster truck?

Or watching Penn eviscerate soap hunk Matt Cedeno from Days of our Lives with his merciless wit?

Hey, as soon as Masterpiece Theatre offers Sheena and Baywatch star Nolin participating in a snake-swim challenge, I'll be pledging my financial support to PBS in a flash.

Until then, I'll make due with Fear Factor.
