Anchorman fans got a surprise treat on Conan last night when Will Ferrell showed up as his newscaster alter ego, Ron Burgundy. Dressed in his signature suit and mustache, "Ron" dazzled the crowd with a little jazz flute before brutally berating Conan O'Brien (paying particular attention to Conan's hair). It all led up to an even bigger surprise: at the end of the segment, Ferrell announced that an Anchorman sequel is definitely happening! As an added bonus, Judd Apatow is confirmed to produce, and stars Steve Carell, Paul Rudd, and David Koechner will reprise their roles as Ron's quirky news team. Watch the clip below!
