Solely basing information on the fact that Casey is handsome (so he MUST be smart) I don't think he'd ever go the Shamwow route. He's probably rapping from his bedroom letting people know he's alive but he doesn't have any legs. He isn't selling anything or making money so I assume he's throwing shit at the wall to see what sticks and works for him.
Casey didn't realize that putting his rap on the 'net just might let other people get at it, but by the time he figured it out it was way too late. The cucumber thing, the erotic poses, and the Sharpie-anointed pictures are the result of an epic troll in which Casey took the supposed attention of someone he knew only from the Internet way, way too seriously.
Caseypedia still up and running? I'm friends with the guy on facebook and honestly don't really follow his life events anymore as they're decidedly less spectacular now. Though I hear he break-danced at his high school reunion last night.
