Michael Leslie Winslow (born September 6, 1958) is an American actor and a comedian known as the "Man of 10,000 Sound Effects" for his ability to make realistic sound effects using only his voice. He is best known for his role as Sgt. Larvelle "Motor Mouth" Jones in the Police Academy series of movies and TV shows.
In the "Li'l Griffins" segment of "Family Guy Viewer Mail No. 1", the guys hear a wolf howling so Li'l Glenn Quagmire tells them to relax. The sounds turn out to originate from Winslow and continues to do a bunch of sound effects. He voices himself.
