Michael Buffer, the announcer behind the "Let's Get Ready to Rumble" catchphrase, wants his fans to tattle on companies who are using the phrase without permission:
"Buffer Enterprises, Inc. now offers a cash bonus to those who report a corroborated unauthorized use [resulting in an actual recovery] of the "Let's Get Ready to Rumble,"® “Get Ready To Rumble”® or "Ready to Rumble"® servicemarked phrases ,any paraphrasing of these marks (including “Get Ready To Crumble,”® “Are Your Ready To Rumble?”™ “Let’s Get Ready To Gamble”™), or use of Michael Buffer’s famous rendition of his copyrighted “Let’s Get Ready To Rumble” recording. This bonus system applies to viable reports [resulting in an actual recovery] of unauthorized use of our servicemarks, copyrights or related rights in or upon TV, radio, the internet, print or in connection with unlicensed products or services such as T-shirts, toys, posters, or other merchandise."
"We constantly deal with violations reported to us by fans around the world or which we witness directly,” states Bruce Buffer. “Our servicemarks and copyrights are invaluable. Just like for a movie studio, these intangible rights comprise the very heart of our business.”
(I am surprised to read that a) Buffer has fans, and b) Buffer has fans that take the time to report these 'violations'.)
