The second season of American animated television series Regular Show originally aired on Cartoon Network in the United States. Many of the characters are loosely based on those developed for Quintel's student films at California Institute of the Arts: The Naive Man From Lolliland and 2 in the AM PM. Quintel pitched Regular Show for Cartoon Network's Cartoonstitute project, in which the network allowed young artists to create pilots with no notes to possibly be optioned as a show. After being green-lit, Quintel recruited several indie comic book artists to compose the staff of the show, as their style matched close to what he desired for the series. Regular Show was picked up by Cartoon Network, who decided to create a twelve-episode first season. Regular Show was renewed for a 28-episode second season. The first episode of Regular Show's second season is "Ello Gov'nor", ending with the season finale "Karaoke Video". The season was storyboarded and written by Sean Szeles, Shion Takeuchi, Benton Connor, Calvin Wong, Paul Scarlata, Kat Morris, J.G. Quintel, Mike Roth, John Infantino, Minty Lewis, Henry Yu, and Dennis Messmer, while being produced by Cartoon Network Studios. The show is rated TV-PG for suggestive humor and occasionally TV-PG-V for mild to moderate violence, including scenes of peril and non-fatal use of firearms, weapons, and explosives. Despite not airing on Cartoon Network's Adult Swim line-up, it is considered more of a traditional adult's animated comedy than a children's cartoon.
