Will the real natto burger please stand up?

Long saga short: (1) Many posts ago, Bot developer and blogger John scanned the Robodex guidebook for BoingBoing, and mentioned he'd omitted a weird ad for what looked like a natto burger. Natto is a sort of smelly, extreme soy food delicacy. Japan's equivalent to limburger cheese. (2) John scanned the ad, and we posted it here. (3) An astute reader pointed out that the ad appeared instead to tout the Kentucky Fried Curryburger. Sloppy, yes, wacky, perhaps, but not natto. (4)Now, Tokyo-ouja blog posts this -- what may in fact be our first authentic sighting of a bona fide nasty Mc-Natto, McDonalds wrapper and all. Aminattoornot.com? You be the judge. Discuss
