This is the final episode to have Gilbert Gottfried voice Dr. Bender and Wendell as well as Wendell's final appearance. Dr. Bender would be voiced by Butch Hartman himself in later episodes he appears in.
The only difference between Chip Skylark and Skip Sparkypants is their hair color and clothes (but they are voiced by the same actor, Chris Kirkpatrick).
This episode reveals that Chip has false teeth instead of real ones. (Dr. Bender was able to pull out his teeth with no problems).
Apparently, all dental-related wishes/magic (including teeth retrieval) can only be handled by the Tooth Fairy herself.
Sailor Moon - The fact that nobody recognizes Timmy Turner with his tiara on is a reference to the fact that nobody recognized the girls when they transformed, yet only their clothes would change and they would have on their head a tiara.
Word of the Episode
Teeth/Tooth is said by a couple of characters throughout the show.
During the song, Chip Skylark twirled through a picture of himself. In the first shot of that picture, his teeth had only one line. When he twirls through it in the next shot, they have lines defining the individual teeth instead of just one line.
This episode, along with "Odd, Odd West", aired on November 30, 2002 in the United States. They were produced in the same year of 2002 according to the credits.
