It's basically an advertisement, but Japan's Weirdest Hotels sure has a lot of very useful information. Who knew that there was a museum of parasites "...many of them spilling out of organs and dead animals ...", let alone a catalogued collections on display of socks, another of laundry.
You can even buy a t-shirt with "raised tape worms that you can feel!", but not over the 'net. All purchases strictly in real time, real place.
Which of course opens up the floodgates for other off-beat museums. There's sure to be a stampede of the naive (I believe P.T. Barnum referred to them as "suckers") wanting to visit - and purchase from the gift shop - of a potential museum of Cell Ring Tones that Caused Madness, a Repository of Retrograde Reading Resources, the Parade of Paradoxical Policies, an Exhibition of Exotic Ephemera, perhaps a Panoply of Polynesian Paperbacks, or a Roving Rendition of Retributive Rants? More?
