||It may not end up revered like "Rudolph the Red-Nosed Reindeer," "The Grinch Who Stole Christmas" or even that awesome televised yule log, but "A Colbert Christmas: The Greatest Gift of All" puts a lot of tongue into a big ol' cheek for 45 minutes and provides more than a few laughs spoofing Christmas specials...Of course, you have to wonder why Stephen Colbert even wanted to do a Christmas special, other than the fact that he likes musical theater, can carry a tune, has great taste in musical friends and, perhaps most important of all, Comedy Central said he could...And so "A Colbert Christmas" allows Colbert to both stay in character (he plays a faux archconservative talk show host on his "Colbert Report") while also having a little fun with his friends...If you're looking for something slick, look elsewhere. "A Colbert Christmas" looks as if it was put together in about an hour for just under a hundred dollars, but that's part of the reason it's so funny. The premise is simple: Colbert wants his own Christmas special and, more important, presents from Santa. But unless he can get to New York for the filming, all will be lost...And of course he can't leave his cabin in upstate New York because there's a bear outside...Clad in a red turtleneck, white Irish cable-knit cardigan and jeans, he prances around the cabin in various states of dismay, blind joy and hopefulness (that he'll get presents). Colbert has a running gag where his pal singer-songwriter Elvis Costello is helping him put on a show...There are mistletoe jokes. There is zaniness. A final piano duet between Colbert and Costello, called "There Are Much Worse Things to Believe In," appears to sum up the point of the special, which is to say it should be fine to have a Christmas special.
