In 1997, the episode Dial M for Monkey: Barequor was banned from airing in America, Canada, Latin America and the United Kingdom due to Spooner being considered a stereotype of gay men and being parodied on Silver Surfer without Marvel's permission and Krunk getting drunk at the end. The full episode remained banned until 1999 when it returned to circulation but with the Monkey episode replaced with the episode: "Dexter's Lab: A Story".
Rerun of the first "What a Cartoon" pilot.
This episode has the same title as the series.
The pilot episode, "Dexter's Laboratory" was re-titled as "Changes" in later airings.
The Dial M for Monkey's fourth episode, Barbequor, was originally aired along with sister episodes "Double Trouble" and a rerun of the original What A Cartoon! short "Dexter's Laboratory" (retitled as Changes), but Cartoon Network accidentally removed the episode due to sexual content for this character. However, it was being replaced by a rerun of 'Dexter's Lab: A Story', from the second season which aired late and features the green letters in the background from the opening and closing titles instead of yellow from the original first season, where the "Produced and Created by Genndy Tartakovsky" animation screen and the new Dexter's Laboratory logo is shown from the show's second season, and features the Hanna-Barbera/Cartoon Network logo reissue at the end of the episode despite being produced by Cartoon Network Studios at that time, replacing the latter's logo from the original first season that are used from The Cartoon Cartoon Show from October 1996 to March 1997, and the ending credits is much thicker than the original first season and features the 1998 copyright to also be produced that year, and 'A Time Warner Company' logo is shown from the second season instead of 'A Turner Company' logo from the original first season. Also, "Double Trouble/Dexter's Lab: A Story/Changes" was included on the Season 1 DVD box set and released on HBO Max but "Barbequor" doesn't. (However, it was available on YouTube and other video streaming releases after "Barbequor" was banned.)
