I received the following email from Joe Mason. Instead of summarizing it, I'll just cut-and-paste the whole thing:
Amazon has a listing for "Hamster Huey and the Gooey Kablooie". The book also has a homepage at http://www.hamsterhueypress.com/, and it's listed as being written by "renowned story teller" Mabel S. Barr.
Hamster Huey is, of course, the fictional book written by "Mabel Syrup" in Calvin and Hobbes. It looks like somebody with a vanity press has ripped off the title (I don't think titles are copyrightable, so this may even be legal). This version of "Hamster Huey" certainly isn't a "classic and much-beloved tale" as the publisher claims, so it's a hoax in that sense. I suspect it may go even deeper, and there is no actual book: "At Ms. Barr.s request, only a limited number of copies of this first edition are being printed, and Hamster Huey and the Gooey Kablooie is sure to sell out soon." That's an easy excuse for not shipping a single copy.
So - is this a vanity press trying to pass off its book as a famous title? Or is someone having a chuckle by tricking Amazon into printing a fake book listing?
I guess the easiest thing to do would be to order the book and see what arrives, but since I don't want to spend the money my hunch would be that it's a real book that's a homage to (or inspired by) the fictional book from Calvin and Hobbes. Though I think there would be some intellectual property issues involved if the author of the book being sold on Amazon hadn't got the permission of the Calvin and Hobbes author. As for the issue about the 'limited number of copies', I think they're referring to copies of the first
edition. Presumably they could print further editions if the first one sold out. But the real ripoff is that they're charging $7 for an 8-page paperback.
