Michael Buffer is the best-known ring announcer for boxing and professional wrestling. He has appeared in more than 20 movies and television shows, such as Rocky V, Rocky Balboa, and Phineas and Ferb. His trademark phrase, “Let’s get ready to rumble!” is literally trademarked. By selling the rights to this phrase to be used in music, video games, movies, and merchandise, Buffer has earned more than $400 million in royalties — much more than he makes from announcing in the ring.
