Future late-night rivals, Conan O’Brien, Jon Stewart and Stephen Colbert kicked off their face-off early with a dance-off during O’Brien’s New York stop of his Legally Prohibited From Being Funny On TV Tour. One by one, Colbert and then Stewart, the latter dressed as “proud Mexican,” took the Radio City Music Hall stage to confront O’Brien, whose new late-night show on TBS will air directly against Stewart and Colbert’s Daily Show and Colbert Report on Comedy Central. The quality of the video is poor but there are a couple of gems in it. My favorite, when Stewart dies at the end, Colbert kneels next to him, whispering: “Jon, before you go… can I have 11 o’clock?” And keep an eye on the two backup singers onstage. They’re having quite a good time.
