According to Benjamin Daniel, the ending sequence in which almost all TGWTG contributors sing Linkara's theme song was accomplished by Lewis Lovhaug e-mailing different verses of the song to each of them to sing, then they sent him the footage to be edited into the episode; Satellite trouble prevented Mathew Buck (Film Brain) from participating.
Not counting the specials, this is the official 100th episode of Atop the Fourth Wall.
