For week two of Celebrity Circus, ex-Brady Buncher Christopher Knight will set himself ablaze as he performs "fire clowning." I wonder how Adrienne Curry feels about this. It's got to raise some suspicions about your husband's sanity if he's willing to set himself on fire for reality TV.

Here's some of the other stupid things the celebs will be doing this week on the show:

Wee Man battling the German Wheel, the same act in which Knight broke his arm. Wee Man will be paired with trainer Vladimir Sizov for a synchronized act. Stacey Dash will perform on the Cerceau alongside trainer Sacha Fedorchev. Dash will be creating a sexy and high-energy routine flying 50 feet above the ground with no safety line or harness. Antonio Sabato Jr. will push himself to the limit doing a hand-balancing act with his partner and trainer Christine Van Loo. There will be no room for errors as any little mistake could lead to serious injury.
