Hotshot computer programmer Ken Gemberling is the top programmer at Ynapmoclive Interactive, but is also remarkably rude, selfish, and arrogant. After dumping beer on his computer keyboard, Gemberling is inexplicably sucked into his computer, landing in the farthest reaches of the internet where he soon discovers that he is in fact "The Chosen One", prophesied to save cyberspace from a devastating virus known as the nanoplague. Joined by a pair of humanoid "programs" named Bit and Byte, Gemberling embarks on an epic adventure to save the internet, return home and unleash the hero within, all the while hunted through cyberspace by ruthless white trash bounty hunter Chains.

Fat Guy Stuck in Internet first appeared as a 2005 web series created by Upright Citizens Brigade alumni John Gemberling and Curtis Gwinn, known as the comedy duo of The Cowboy & John.^[1] Originally titled Gemberling, the series followed the same storyline and major plot points of its television adaptation, featuring much of the same cast (with the notable exception of Katie Dippold in the role of Byte) though with a considerably lower budget and more profanity. Aired in five-minute episodes as part of Channel 102, Gemberling became Channel 102's longest-running original series, lasting a total of eight episodes including a 17-minute finale.^[2] The shorts also aired as part of Fuse TV's Munchies.^[3]

In January 2007, Cartoon Network announced that they had commissioned Gemberling and Gwinn to create a series based on Gemberling as part of the Adult Swim programming block.^[3] Adult Swim made the decision to rename the series as Fat Guy Stuck in Internet, a title which both creators disliked.^[4] The entirety of the series was filmed and produced inside of a warehouse in Bushwick, Brooklyn.^[5] On May 30, 2008, Gemberling and Gwinn premiered Fat Guy Stuck in Internet before a live audience at the Upright Citizens Brigade theatre in New York City.

Fat Guy Stuck in Internet uses a mix of greenscreen effects, hard sets, miniatures, matte paintings and computer animation to create the show's cyberspace environment,^[6] though carries over many of the intentionally low-budget props and special effects from the web series (e.g. broom handles being used as laser-shooting weapons, etc.).

The basic premise of Fat Guy Stuck in Internet is a parody of the film Tron, from which the series also borrows several visual elements.^[7] Gemberling and Gwinn have noted further parody and stylistic influence taken from The Matrix, Star Wars, The Lord of the Rings and Stephen King, in particular his Dark Tower series.^[5][8][9]

Fat Guy Stuck in Internet received mixed reviews from viewers and critics. The A.V. Club, having reviewed every episode as part of their "Adult Swim Sunday" column, was one of the series' harsher critics, primarily criticizing the show's "cheap" writing, poor movie parodies and John Gemberling's "smirking, mediocre" performance.^[11][12] As the series progressed, however, the reception became a bit warmer, with later episodes being called "not completely terrible" and "not entirely unpleasant" to the final episode being described as "going out with a bang", the reviewer admitting "for a couple minutes, I actually found myself engaged".^[13] Time looked positively on the series, noting the show "delivers", being "striking-looking and even good-hearted in its own bizarre way".^[14]
