Cut-away of the Earth, showing the location of Deep 13.

Deep 13 was a subbasement of Gizmonic Institute and, according to former SOL janitor Joel Robinson, highly radioactive as a result of being close to the Institute's atomic pile. Dr. Clayton Forrester and Dr. Laurence Erhardt began using it for their work in order to avoid detection at Gizmonic. Some time after Dr. Erhardt's departure and the arrival of TV's Frank, the Mads began living in Deep 13 and, eventually, cut all ties to Gizmonic.

There was a neighboring Deep 12 whose tenants once included two "foxy ladies."

Two resident Mole People, Gerry and Sylvia (named after Gerry and Sylvia Anderson), also served as Dr. Forrester and Frank's assistants in Season 2 and Season 3.

In the final Comedy Central episode, Dr. Forrester shut down Deep 13 and moved back in with his mother after his funding was cut.

Behind the scenes

The show never explained from whom Forrester was receiving funding. However, series creator Joel Hodgson (who also played Robinson), when pressed in an interview for the Satellite News, gave a plausible explanation: the Mads were selling the show to basic cable providers (effectively making it a show within a show). This storyline was bolstered by several "host segments" from the KTMA season through season 7 that discussed the internal show's ratings. But as Hodgson cautioned in the interview, such storylines should be taken with a grain of salt, as recommended by the show's theme song: "Just repeat to yourself, 'It's just a show / I should really just relax'".[1]
