Country star Jimmy Buffett is suing a U.S. theme park owner, claiming it stole a name from the nickname of his fans. Buffett claims the Six Flags's Carrothead Club infringes his trademark on Parrotheads, a name associated with his Hawaiian-shirt-wearing devotees. The move has stunned Six Flags, responsible for 20 theme parks. Representative Wendy Goldberg tells New York gossip column, "I'm not sure how the concept of children in foam carrot hats is going to be confused with significantly older Hawaiian shirt-wearing, margarita-swilling Parrotheads. Clearly imitation wasn't what we had in mind!"
