This episode aired on November 11, 2005, and featured a storyline where Orel's father, Clay, becomes increasingly frustrated with his son's moralistic behavior. The episode culminated in Clay committing a series of violent acts, including shooting a bear, burning down a church, and threatening Orel with a gun.
The episode was highly controversial, with many viewers criticizing its depiction of violence and its lack of humor. As a result, Adult Swim pulled the episode from its schedule and canceled the show.
It's important to note that while "The Angriest Man in the World" is often cited as the reason for the show's cancellation, the show was already struggling with low ratings and negative feedback. The episode simply exacerbated these issues and provided Adult Swim with an excuse to pull the plug.
