Christmas is only four days away, and while a handful of shows are already on holiday hiatus (you won't see new episodes of "The Daily Show," "The Colbert Report" or "Jimmy Kimmel Live!" until 2010), there are plenty of shows delivering original content for the first three days of the week before reverting to repeats on Christmas Eve and Christmas Day.
Adam Lambert continues his quest to get a copy of For Your Entertainment in every home with an appearance on Monday (December 21) night's edition of "The Jay Leno Show." Leno will also welcome Dane Cook on Tuesday (December 22) night's episode. "The Late Show with David Letterman" features a performance from Colbie Caillat on Tuesday night, while "The Tonight Show" will feature live sets from Silversun Pickups on Monday and Kid Cudi (fresh off the Lady Gaga tour) on Tuesday.
Meanwhile, Jimmy Fallon will talk to Martha Stewart on Monday (perhaps she'll talk about her recent team-up with Snoop Dogg) and will have the Muppets in the house on Wednesday (December 23). In the daytime world, "The View" will have Boys Like Girls on Tuesday and Mary J. Blige on Wednesday (as odd a juxtaposition as can be, really). And anybody looking for the best repeat on Christmas Eve, look no further than "The Colbert Report" on Comedy Central, as they will re-air the episode featuring host Colbert's tag-team with Alicia Keys on a suburbanized version of "Empire State of Mind." What better way to welcome Santa Claus than with a toast to New York and some verses about private schools?
