Yvonne Wilder and John Aprea make their first series appearances as Irene and Nick Katsopolis, the bombastic parents of Uncle Jesse (John Stamos). After selling his first TV jingle, Jesse decides to give up his job with the family's extermination business and become a full-time musician--if only he can work up enough nerve to tell Irene and Nick. Meanwhile, a terrified Stephanie (Jodie Sweetin) prepares to have her first cavity treated by the family dentist (Peter Kwong). ~ Hal Erickson, Rovi
