 The final scene of the episode showing Mayor West delighted that he has grown sausages (although it is really Brian's waste) was one of several possible ending scenes for the episode; alternatives included Brian leaving his waste at Cleveland Brown and Mort Goldman's house, but in the end, the production crew decided to go with Mayor West.In addition to the regular cast, actor Roy Scheider played himself on the toilet training video, and voice actors Barclay DeVeau and Wally Wingert guest starred as various characters in the episode.Recurring guest voice actors and writers Danny Smith, Alec Sulkin, and John Viener made minor appearances.
