Trivia / The Simpsons S 9 E 18 This Little Wiggy

• Acting for Two: Nancy Cartwright voices 80% of the cast in this episode, voicing Ralph and Bart, as well as Nelson Muntz and Kearney, meaning that they're talking to themselves for much of the episode's runtime.
• In Memoriam: The episode was dedicated to animator Sunni Walton.
• What Could Have Been:
  • When Bart looks through the police records, he finds Homer's and comments, "Wow, Homer's been in jail six times." Originally, the line after that was, "Aw, he killed a swan at the zoo," but the line was changed to "Aw, Mom's only been in jail twice."
  • The episode original climax involved Bart, Ralph, and Homer trying to make a plan to save Mayor Quimby.
• Write What You Know: The robot that was introduced early in the episode was influenced by writer Dan Greaney's experiences working with a USA Today themed robot. While at a baseball game with the robot, the robot led the stadium in singing "Take Me Out to the Ball Game". The robot was not well-received, and the spectators threw objects at it. The robot's operator had to stay close to the robot during the baseball game, and was also teased and bothered in the same way as the operator in the episode.
