Zach Galifianakis shows up on the sets of various NBC shows (with fictional scenes and archival footage) either talking to the actors, or just standing in the background, finishing with a clip from a 1984 SNL episode hosted by Robin Williams showing a bearded child (supposedly Galifinakis) and the words: "Zack Galifinakis: on TV for over 30 years." The NBC Website has posted this as a Digital Short, despite that it didn't have the "SNL Digital Short" title screen on the televised version. (thetvdb.com)
