A new theory proposed by 4chan's music board /mu/ suggests that Neutral Milk Hotel's Jeff Mangum traveled back in time to save Anne Frank from the Nazis and brought her back to the Eighties where she posed as his sister, Coraline.

TheIthacan points out that 4channers stumbled upon this theory upon finding photos from Mangum's high school year book and noticing that his sister bears a striking resemblance to Anne Frank. Frank's life story was, of course, the basis of Neutral Milk Hotel's beloved album In the Aeroplane Over the Sea.
