You've seen the comedy bit, now you can see the behind the scenes rehearsal and outtakes from the infamous Conan O'Brien/Jon Stewart/Stephen Colbert "Who Made Huckabee First" late night fight.

Late Night Underground, the official Late Night with Conan O'Brien writers blog, has a really funny clip showing how the three late nights hosts filmed their epic battle in the hallways and stairwells of NBC. You see the various times the three smashed fake bottles over their heads (and at one point one doesn't break and seems to be a real one), you see Stewart asking if they can change one of the signs in the hallway, and you also see Colbert come out of a room (maybe a dressing room?) that has a Colbert Report sign on it. Not really sure what that's all about.

There's also a nice shot of them just sitting on the stairwell that would make a nice poster for fans of the three of them, and the last shot has the three reminiscing a bit about David Letterman's tenure in the studio and Saturday Night Live.
