Disney and Lucasfilm have been using the out-of-this-galaxy popularity of Star Wars to raise money for charity, and with just a week left in their very first campaign, theyve enlisted Jon Stewart and Stephen Colbert to help promote the cause. Fortunately, Stewart and Colbert are apparently huge Star Wars fans — huge enough of fans to duel over the title of who the series biggest fan truly is. The two have put together a short, hilarious video for the campaign, and its not to be missed for fans of the two comedians. Why are you using Darth Vaders lightsaber?
