12 oz. Mouse is an American animated comedy show on Cartoon Network as part of the Adult Swim late night programming block. The show centers around the antisocial actions of a 12 oz. mouse (also known as Fitzgerald Mouse, according to the "bump" that aired just before the program). It was created by Matt Maiellaro, a co-creator of Aqua Teen Hunger Force, Adult Swim's most popular original show. 12 oz. Mouse premiered on June 19, 2005 at 12:30 a.m., with an encore presentation at 3:30 a.m. It has yet to be announced by the network whether it will become a regular show on the Adult Swim lineup.
The show is also known as "oz.Mo" for the title sequence, in which the "camera" is so close to the "12 oz. Mouse" title card that only the characters "oz. Mo" are visible.
According to the network, the show is about a 12 oz. mouse who is fond of beer and caught in a world of espoinage and love, and unknowingly delights in odd jobs.
The style of the show is of a crude children's drawing and limited motion. The brandishing and usage of firearms, drinking alcohol to excess, and indifferent homicidal acts are common activities of the 12 oz. mouse. As a character, the mouse is a heavily-drinking, arrogant, indifferent womanizer who, in the pilot episode, instead of completing his temporary job as a chauffeur for a pink box that wear sunglasses but has no eyes, connives his customer into making a pornographic tape.
Other characters include a shark who runs a temporary employment agency who hires the 12 oz. mouse for various odd jobs.
During the premiere, it was hinted in the Adult Swim "bumps" that Matt Maielloro had been intoxicated when he came up with the idea for the show, which is how the crude art reminiscent of "a 4-year old on drugs" made its way into the show.
