Who better to help Jon Stewart prepare for his big debate with Bill "Papa Bear" O'Reilly than the man who parodies him on a nightly basis?

That's why Stewart got Stephen Colbert to ride into his studio (via shirtless manservant) on Wednesday night to simulate Saturday's big debate. Colbert put on the larger-than-life conservative pundit charm and schooled Stewart in the ABCs of debating: Always. Be. Attacking. There's even a special appearance by Clucker Carlson (Tucker's poultry cousin).

Watch how Colbert preps Stewart for what will surely be an intense debate this weekend above.
