One upon a time (2002), in a land called VH1, a then-beardless Zach Galifianakis had his own late-night talk show called Late World with Zach that was canceled after nine weeks.

Last night, for a brief, shimmering four-and-a-half minutes, Galifianakis found himself playing the late-night game once again — aptly, on NBC's Late Night.

Switching seats — and bodies — with host Jimmy Fallon, Galifianakis showed the late world that he's more than ready for another shot at a talk show gig, if only for his uncanny ability to make things incredibly awkward for all involved.
