I don't want to sound like a Japanophile or anything, but it's Rockman products like these that made me wish I had spent my youth in Japan. I present to you hand crafted Rockman bed sheets.
Such an obscure product is currently available for bidding at Yahoo! Auctions for the low low price of 700 Yen ($7.30). Cheapest bed sheets ever? You bet. Word to the wise however; these are used so there's no telling where they've been. Be sure to wash!
