This article is of a cast or crew member who worked on Tiny Toon Adventures who is still living to this day, and is written from a real-world perspective.
John Kassir (born October 24, 1957) is an American actor and voice actor, best known as the voice of the Crypt-Keeper in Tales from the Crypt as well as the second voice of Buster Bunny.
When Animaniacs was cast, Charlie Adler was not happy that minor voice actors such as Frank Welker and Rob Paulsen were cast and he was not, so he left. John took over the role of Buster for the rest of the season. Charlie returned to voice Buster for an unproduced Tiny Toons video game. John also voiced Buster for the video game, The Great Beanstalk.
