Quintel for Cartoon Network. The show centers on the lives of two working-class friends, a blue jay named Mordecai and a raccoon named Rigby—both employed as groundskeepers at a local park.

10. Sheep in the Big City (November 17, 2000 – April 7, 2002)

Sheep in the Big City was created by Mo Willems for Cartoon Network. The show centers on a runaway sheep, Sheep, in his new life in "the Big City". It also features several unrelated sketches and shorts, similar to The Rocky & Bullwinkle Show and The Fugitive. With an emphasis on more "sophisticated" (in particular, literal) humor, using multiple forms of rhetoric from the characters to the plots, it was more popular with older audiences. It was also unusual in featuring many comic references to film-making and television broadcasting. At the time, the premiere of Sheep in the Big City was the highest-rated premiere for a Cartoon Network original series.

The pilot episode of the series was aired on August 18, 2000. The popularity of the pilot convinced the network to order a half-hour series, which ran for two seasons from 2000 to 2002, with 13 episodes in each season.

9. Codename: Kids Next Door (December 6, 2002 – January 21, 2008)

Using their codenames (Numbuh 1, Numbuh 2, Numbuh 3, Numbuh 4, and Numbuh 5), they are Sector V, part of a global organization called the Kids Next Door.

The series came about as the result of a viewer's poll by Cartoon Network. It ran from 2002 to 2008, with six seasons and 78 episodes. It also had two television films, Operation: Z.E.R.O. aired in 2006, and the series finale Operation: I.N.T.E.R.V.I.E.W.S., aired in 2008.
