The top of my storage cabinet at work is covered solely in Badtz-Maru stuff, including the lunchbox, two toothbrushes, and several metal boxes large and small, some of which I've never been able to determine the purpose of. Plus i have the wallet, the keychains, the temporary tattoos, and the car stickers. And most recently, i am always seen with the jumbo DJ bag. I have a few Keroppi items, but Badtz is my boy. Although Obey Giant is up there as well (i have six of the posters).
My wife and i fell in love with Sanrio stuff a few years ago when a toy store here in the Outer Richmond district of San Francisco was going out of business; we just admired the quality of the design. Plus, this is a largely Asian-American neighborhood, so this stuff isn't that unusual (um, well, at least for the children around here; 37-year-old white guys is a different story). I especially like the fact that the Badtz stuff often features him on the object using the object; the wallet pictures him holding a sack of cash, the toothbrush holder shows him brushing his teeth, and he's spinning records on the DJ bag.
I have no idea why these iconic figures have latched into my brain so effectively, but my wife knows when she goes out of town that when she gets back I'll have bought books, records, and Badtz-Maru stuff.
Believe nothing, O monks, merely because you have been told it...or because it
is traditional, or because you yourselves have imagined it. Do not believe
what your teacher tells you merely out of respect for the teacher. But
whatsoever, after due examination and analysis, you find to be conducive to
the good, the benefit, the welfare of all beings--that doctrine believe and
cling to, and take it as your guide.
--Gautama Buddha, Indian philosopher (536?-483? B.C.)
