Copyright is a tricky thing. On the one hand, big guys like the Associated Press has absolutely no concept of it. On the other, little guys like the Naked Cowboy have totally learned how to use it to their advantage. Having sued Mars Inc. over a M&M’s billboard in Times Square that showed a blue M&M dressed in his trademark boots and briefs, a federal judge just ruled that the case can move forward, leaving the city’s most famous underwear strummer, real name Robert Burck, thinking, “I’ve got $4 million coming my way.” And he could very well be right. But throughout this whole ordeal we can’t help but thinking Burck, who has auditioned for everything from American Idol to Star Search, has based his entire business model on this very opportunity: Get so quirky famous that a brand would pay him for an endorsement deal (actually, he’s appeared in Chevrolet and Guinness ads), or they’d try to rip him off so bad he could sue. Brava.
