Admittedly I've spent too much time pondering the likes of Doo Doo. However, much like our ynotdivein mentioned I'd say he's quite the whimsy.
Take away the threats to police and that concealed firearm he may be appealing if you're 20 years old or so.
More things I learned about Doo Doo:
He lived in Sleepy Hollow, Illinois
He travelled quite a long ways by train hopping.
He claims to be a peaceful fellow.
Is he part of the 99%? I'd say "He*l yeah". Am I jealous of his wanderlust? You know it. Oh and he sure does resemble the Johnny Depp of many roles with a dash of Orlando Bloom thrown in.
Since it's 2012 I publically apologize for making fun of BeBopaloopa. I wish I had the guts to change my name to something like that. Maybe he needed that forearm to ward off pirates?
BTW, anyone going to buy his art work?
