Conan O'Brien, Stephen Colbert, and Jon Stewart resorted to fisticuffs while appearing on each other's shows to settle a mock feud over who made Mike Huckabee. (Watch video clip)

The fight began a few weeks ago when O'Brien claimed he was responsible for Huckabee's success in the presidential primaries because he made Chuck Norris, who, in turn, made Huckabee. Therefore O'Brien made Huckabee. Colbert, for his part, claimed that Huckabee's success was due to the "Colbert bump" Huckabee received after appearing on his show.

O'Brien and Colbert sniped back and forth, and later Stewart got into the mix, arguing that he made O'Brien when he hosted the young comedian on his MTV program in 1994. Therefore, by the "transitive property of Huckabee," if O'Brien made Huckabee, and Stewart made O'Brien, then Stewart made Huckabee.

O'Brien tried to settle matters the other night by proving that he made both Stewart and Colbert. As evidence, he showed his audience a photo of him as the doctor who delivered Stewart and Colbert. Then he warned that if either of them brought up the issue again, he would come to their "tiny, little studio, and kick "some Comedy Central ass."

On Monday, O'Brien made good on his promise. Watch the hilarious footage of O'Brien throwing down with Stewart and Colbert on The Daily Show and the The Colbert Report, culminating with an all-out brawl on Late Night with Conan O'Brien -- complete with blowtorches, baseball bats, and bricks.

When the fighting was over, Huckabee had the last word. "Let's be clear: None of these guys made me," Huckabee said via satellite. "This great nation made me. So vote for me. God bless America and forget these three idiots."
