A japanese tramp. In either real-life or in a film.I've seen a few (in Japan), they are quite contempt for tramps, very neat cardboard box sleeping rooms (about the same size as the capsule hotels!) they even put their shoes outside to keep the usual tradition of no shoes in the house. Discarded food from convenience stores keep them quite well fed too.
They could still do with a shower and a shave though.
I saw a Chinese albino once, proof two wongs can make a white.Had an Iraqi albino follow my team through a market once, freaked us out, the locals seemed to part like he was Moses crossing a sea!
