What if William Hanna and Joseph Barbera worked for Warner Bros. after leaving MGM and retained the rights for Tom and Jerry/Harvey Birdman, Attorney at Law

Harvey Birdman, Attorney at Law is an American animated television comedy series created by Michael Ouweleen and Erik Richter for Adult Swim. The show revolves around the activity of the Sebben & Sebben law firm, which is staffed mainly by characters who had originally been featured in past Warner Bros. Animation shows, most notably Birdman and the Galaxy Trio.

Harvey Birdmans pilot first aired on Cartoon Network on December 30, 2000. On September 2, 2001, the series moved to Adult Swim, continuing for four seasons and 46 episodes before ending on July 22, 2007. The show is also a spin-off of Space Ghost Coast to Coast, where Birdman got his first name from. Both Space Ghost and Birdman original series were based on action/adventure script and, decades later, applied in comedic contexts.

Premise
Harvey Birdman, Attorney at Law features ex-superhero Harvey T. Birdman of Birdman and the Galaxy Trio as an attorney working for a law firm alongside other cartoon stars from 1960s and 1970s Warner Bros. cartoon series. Similarly, Harvey's clients are also primarily composed of characters taken from various Warner Bros. animated series, such as the Looney Tunes/Merrie Melodies franchise, Scooby-Doo, The Flintstones, among others. Many of Birdman's nemeses featured in his former cartoon series also became attorneys, often representing the opposing side of a given case.

Harvey usually fills the role of a criminal defense attorney, though he will act as a civil litigator or other such job when the plot calls for it. The series uses a surrealist style of comedy, featuring characters, objects, and jokes that are briefly introduced and rarely (if ever) referenced thereafter. Also, because the series relies heavily on popular culture references to classic television animation, Harvey Birdman, Attorney at Law constantly delves into parody, even featuring clips of these series or specially-created scenes which mimic the distinctive style of the animation being referenced. Harvey Birdman, Attorney at Law is the first Warner Bros. Animation and Williams Street cartoon to maintain continuity through the entire series. Various episodes reference Harvey's (or another superhero's) former crimefighting career. The episode Turner Classic Birdman even serves to bridge the gap between Birdman and the Galaxy Trio and Harvey Birdman, Attorney at Law.

Instead of rigid plot structure, much of the humor is derived from the fact that superheroes and supervillains are given more realistic and human qualities, such as a mad scientist named Dr. Myron Reducto, who becomes a paranoid prosecutor. Also, several of the plots revolve around the popular myths about classic Warner Bros. characters, such as Shaggy and Scooby-Doo being stoners and Magilla Gorilla being a homosexual prison convict.
