Mini-documentary YouTube channel Great Big Story just uploaded ripped into our nostalgic hearts with their newest video. Great Big Story reached out to a few voice-over actors and asked them how they got their gigs, such as Elwood Edwards (the guy behind AOL’s iconic “You’ve Got Mail” greeting), Charles Martinet (voice of Super Mario) and Billy West (voice of Ren, Stimpy, Doug and a ton of Futurama characters). Watch the short doc down below, learn a bit about your favorite voices, and take a trip back in time with your childhood.
