Conan O'Brien Conan O'Brien

Cheers to Conan O'Brien for his triumphant return to New York City. Performing a mere 200 feet away from NBC's 30 Rock, his old place of employment, Conan rocked Radio City Music Hall with a high-energy, star-jammed extravaganza. Proving his career has risen from the dead, he joined Columbia University alums Vampire Weekend for a rousing version of "Walcott," then brought out New York's — okay, New Jersey's — own Stephen Colbert for a hilariously under-rehearsed dance-off. When Colbert went down with an alleged hamstring injury, who should appear but Jon Stewart, inexplicably dressed as a Mexican waiter, to finish the battle. And the stars kept on coming, thanks to the ever-popular Walker, Texas Ranger lever, which was yanked by Bill Hader (who busted out a bit of his latest breakout Saturday Night Live character, Stefan), The Office's John Krasinski (who once worked as an intern on Late Night with Conan O'Brien) and Paul Rudd. If Conan can command this kind of star power on his new TBS talk show, Jay Leno had better watch out.

Are you psyched for Conan's new show?
