S1·E11 Next Time, Phone Ahead / Nerdator

The cartoon is cut short when the show's lazy writers decide to end the episode early to show more 'Animaniacs' reruns. However, Steven Spielberg won't stand for it, and unleashes his vision to finish the cartoon right. Dexter Douglas soon meets a strange alien named Mo-Ron, who becomes lost from his alien friends. Dexter helps Mo-Ron phone home, and soon all is well-that is, until the long distance charges roll in.
