NEW YORK (AP) -- The bad boys of "South Park" will make mischief for years to come.
Comedy Central says "South Park" co-creators Trey Parker and Matt Stone have signed to extend the animated series an additional three seasons, through its 20th season in 2016.
The network announced Wednesday that Parker and Stone will continue to write, direct and edit every episode of "South Park," just as they have since the premiere of the series in 1997.
Earlier this year, the duo met with tremendous success on Broadway with their hit musical, "The Book of Mormon."
The Emmy- and Peabody Award-winning "South Park" views the world through the eyes of Stan, Kyle, Kenny and Cartman, four bratty youngsters in an unhinged Colorado town.
