While attending the Quahog Airshow, the Griffins lose Stewie. A passing radio worker consults Brian over the prospect of beginning a stint as a radio host, after hearing him call for Stewie over the loud-speaker. Brian then begins his radio career, but is told to seek the aid of Stewie, after he had made a prank call to Brian while he was on the air, much to his annoyance. Meanwhile, Thelma Griffin, Peter’s mother, visits the household, telling Peter she has split up with his father, Francis Griffin, to Peter’s dismay. She begins a sexual relationship with local news anchorman Tom Tucker, but the couple break up just as Peter is beginning to adapt to having a new father. Brian later resigns from his radio career for unspecified reasons.
