Apple has one last Get a Mac ad to air, possibly as a part of today's WWDC keynote, rumors claim. The short is said to have been filmed at a bar in Greenpoint, Brooklyn last week, with John Hodgman (PC) as a bartender, attempting to get someone drunk in order to get his hands on an Apple prototype. Although it is not certain where the ad will be aired, actor Justin Long (Mac) is said to be notably missing.
