The EFF filed a suit against Barney's lawyers, who have spent almost five knuckleheaded years threatening a guy named Justin Frankel [Dr. Justin Frankel, thank you very much], making dubious claims that his online parody about "The Enemy's" true nature infringed on their client's copyright. [the image above is from Frankel's original page.]
I sure hope the legal definition of parody doesn't rely on how funny something actually is. But I guess you have to consider the crap he had to work with. The legal back and forth, meanwhile, is pretty entertaining.
