Saturday Night Live

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.
