In what appeared to be a less-than-friendly act, NBC is yanking Friends spin-off Joey from its Thursday-night lineup as part of a major revamp aimed at reviving the network's once invincible Must-See-TV comedy array. The network said Thursday that beginning Jan. 5, Joey will be replaced by Will & Grace. Four Kings, a new sitcom from Will & Grace creators David Kohan and Max Mutchnick, will follow at 8:30 p.m. The network will move My Name Is Earl, its only successful new entry of the season, into the key 9:00 p.m. timeslot, followed by The Office at 9:30 p.m. The network's long-running E.R. will remain in the 10:00 p.m. period. "Thursday night is what NBC is about," NBC Entertainment President Kevin Reilly told today's (Friday) New York Times. "This is just about going back to a comedy block." The new moves also bump Donald Trump's The Apprentice off the schedule, although Reilly told the Times that he expects it to return in the spring -- but probably not on Thursday nights. He also said that NBC will bring back the comedy Scrubs on Jan. 3 at 9:00 p.m., scheduling two original episodes back-to-back each week.
