Uh-oh! Looks like Conan O'Brien and Stephen Colbert's tiff over who's really responsible for Huckabee's fame has reached a new level- we're talking the ass-kicking kind! Last night, both Colbert and John Stewart appeared on Conan's show to duke it out like men. Oh, and it was ugly too- bats were swinging, trash cans were flying and they even busted out a blow torch. It was no holds barred, we tell you!
