I used to work as a newspaper assembler (subber, for those industry insiders) with this guy who lived in his dodge caravan. He smelled like shit, onions and lysol mixed together. When people would make fun of the way he smelled, he would go to his van and spray himself with air freshener.... Of course the jokes would get worse when he'd come back from doing that, but whatever. He used to wear red bib-overalls and a blue shirt everyday and he had big dirty curly hair so we called him dirty mario.
The fucked up part was his family lived in his van too, with a daughter about 10 years old and a son about 4 years old, and a nasty wife. Child welfare services eventually took his kids away though, which was good IMO.
