A bad bout with the flu lands Frasier in bed. Meanwhile, Roz becomes convinced that Gil, the station’s restaurant reviewer, is gunning for Frasier’s premium time slot after he jumps at the chance to “sub” for the ailing doc. Frasier persuades a hesitant Niles to “pinch hit” for him.

Much to Frasier’s surprise -- and dismay -- Niles shines in his first radio stint. This makes Frasier even more paranoid about his job, and he dreams of “bombing” upon his return to the show.

Awakening from his nightmare, Frasier heads to the station and bursts in on Niles, accusing him of trying to steal his show. When he grabs the microphone and begins taking calls, station security guards must carry Frasier, kicking and screaming, out of the studio and back to his sick bed.
