obvious Photoshop job, there are at least three real five-neck guitars, all of them made by Hamer for Rick Nielsen from Cheap Trick. So now we know. More. If you want three necks, you'll have to look here.
UPDATE: Ned writes: That is one of the three guitars made for Rick Neilson. The gal holding it is Kaia from The Butchies. They played a show with Cheap Trick in 2004, which is where the photo was taken... see here for all the details. Thanks Ned!
