DON'T MISS: "A Christmas Story Live!" – Break out the leg lamp and guzzle some Ovaltine. Not to be confused with the 1983 film that annually airs in 24-hour marathons, this is a live version of the Broadway musical adaptation of the Yuletide classic about Ralphie Parker and his dysfunctional clan. Ralphie, oh so desperate for a Red Ryder BB gun, is played by 11-year-old Andy Walken, who beat out 350 other boys in a nationwide talent hunt. The cast also includes Maya Rudolph, Matthew Broderick, Jane Krakowski, Chris Diamantopoulos and David Alan Grier. 7 p.m. Sunday, Fox.
