Harvey Birdman: Jailbirdman was a lost Flash game that could be found on Adult Swim's website in 2003.
The game was presumably based on the "Deadomutt" two-parter episode of Harvey Birdman, Attorney at Law, in which Harvey goes to jail.
In 2004, the game was joined by another one, Habeas Dorkus. This, too, is lost.
Going to the page of the game on Adult Swim's site using the Wayback Machine only presents you with a pre-loader, similar to fellow lost Cartoon Network game Toonami: Trapped in Hyperspace.
Fortunately, it ended up on Flashpoint, the Flash game preservation project, along with "Stop That Sandwich" and "File Frenzy."
