Michael Winslow is known as the "Man of 10,000 Sound Effects," and not without good reason. As this video shows, Winslow is clearly master of vocal effects, effortlessly mimicking Robert Plant's trademark wail as well as the unmistakable crunch of a Jimmy Page guitar riff.
In case you didn't recognize him right away, yes, Michael Winslow is indeed Sergeant Larvell "Motor Mouth" Jones from "Police Academy (I-VII)." He's also starred in various other movies, cartoons, and other productions. In many cases he can provide the sound effects for his scenes, which filmmakers like Mel Brooks have taken advantage of to keep production costs lower. Along with all of that other work, he also takes time to be a motivational speaker.
