I have that black tee that looks like the cover of Metallica's "Ride the Lightning". Also have the smiley face Satoshi tee that looks like the cover of that Nirvana album. Bought them from Lightning.store because I think they look cool. I'm not concerned with being mugged. Right now, I think the term "Satoshi" is too obscure, but I think my tee will make some people curious.
