F.A.R.E.W.E.L.L. Final Animated Radical Episode Will Exit Long Lifespan: Codename: Kids Next Door ends its six-season run. No, that's not the operation title (fooled you, adults!) Airing on the Cartoon Network since 2002 after winning a viewer's poll, the animated series follows the missions of five kid operatives known by their "numbuhs" and operating from the high tech, top secret Sector V treehouse.

The 21st of January opens with a twelve-hour marathon at 6:00 am Eastern (5:00 Central). This includes show favorites from the series creator Mr. Warburton (Tom Warburton). The one-hour series finale, "Operation: I.N.T.E.R.V.I.E.W.S.", will air at 7:00 pm Eastern (6:00 Central). Will Numbuh One (Nigel Uno), Numbuh Two (Hoagie Gilligan Jr.), Numbuh Three (Kuki Sanban), Numbuh Four (Wallabee Beetles), and Numbuh Five (Abigail Lincoln) triumph against adulthood?
