Claude Maginot is a classically-trained actor who is ashamed at his recent forced career change, a successful audition for the part of the father in Just the Five of Us, a fictional sitcom with a ridiculous premise involving a "mix-up at the adoption agency" and "three zany new house guests". He resents Just the Five of Us, calling it "commercial dross". Both this sitcom and his unsuccessful interpretive dance performance, In the Future, There will be Robots, are advertised on other stations. He is interviewed on KCHAT to promote In the Future, There Will Be Robots.
During a radio ad for a musical in GTA IV, the musical is said to be taking place in the Maginot Theatre, implying that the theater was named after Maginot, or it is just a reference to GTA Vice City, as the GTA III era and GTA IV era are not related.
