You might not know Michael Buffer by name, but trust me, you know his work:
Buffer came up with the catchphrase "Let's Get Ready to Rumble" thanks to a little inspiration from Muhammad Ali, who used to say, “Rumble, young man, rumble.” Buffer also credits Sal Marchiano, another announcer with similar catchphrase: “Well, we’re ready to rumble.” In the early days, Buffer just worked the phrase in subtly as a part of the sentence he was saying. “I was almost afraid that I shouldn’t be too dramatic with it, like I didn’t want to bring attention to myself,” he told Good Morning America.

He claimed the line as intellectual property in 1992; it has since made him a millionaire 400 times over.
