Hollywood's noble War on Christmas continues with the Morgan Spurlock–produced documentary What Would Jesus Buy?, out this Friday. (And to answer the filmmakers' question, probably a Nintendo Wii.) The film, directed by Rob VanAlkemade, follows New York's own Billy "Reverend Billy" Talen and the members of his Church of Stop Shopping as they battle commercialization and overconsumption at Christmastime. In our exclusive clip, Billy and some carolers sing the wrong words to "Joy to the World" before an unsuspecting suburban family. Enjoy!
