Tim & Julie McNally-Cahill were also writers for the show: they would later go on to create My Gym Partner's a Monkey.
Keep Circulating the Tapes: Up until June 2016, when a DVD set of the entire series was released. However, the version that's been released has the "Megalomaniacs" episode with the "General Custer's Last Stand" sketch and not the "Convert or Die" game show parody.
Kids' Meal Toy: Subway had a set of four toys in 1999. These consisted of a viewfinder, a compass, a changing image block, and a notepad.
Recycled Set: In some episodes, the house of the Randy Beaman kid from Animaniacs is used.
Screwed by the Network: The show's time slots kept changing during its inaugural year on Kids' WB! and it had the unfortunate timing of being on around the time that Pokémon: The Series was becoming insanely popular and the English dub went from being syndicated to airing on network TV.
The cameos by Looney Tunes stars Porky Pig, Daffy Duck and Foghorn Leghorn have them voiced by Billy West (who also reprises Bugs and Elmer for their cameos) instead of their usual actors at the time* Bob Bergen, Joe Alaskey and Greg Burson, respectively.
Miscellaneous trivia:
Bruce Timm designed some of the characters; most notably, Lucky Bob, who was a caricature of crew members Dan McQ.
65 episodes were planned, but only 52 were made due to the show going overbudget.
Although the portrayal of Genghis Khan by an expy of John Wayne was meant to be humorous (as they normally have expies of Hollywood actors and other celebrities portray historic figures in a humorous manner), John Wayne REALLY did portray Genghis Khan once.
The Green Eggs and Ham parody with George Bush's hatred of broccoli was recycled from a cancelled Animaniacs script.
