Gopher from Winnie the Pooh
Gopher is a Bricklayer, Builder, Excavation and Demolition Expert (but 'not in the book'). He lives in tunnels under the 100 Acre Wood. He is often equipped with a helmet and toolbox and loves dynamite. He never looks where he is going and often falls into his own tunnels. Whistles while he's speaking.
Gopher is the only character in the Disney version of Winnie the Pooh, that wasn't in the original story of A.A. Milne. It is believed that when Disney bought the rights to Winnie the Pooh, they thought that it wasn't 'American' enough, so they created a character Americans could relate to.
One of the first lines Gopher utters during his first appearance in the Disney cartoon is: "I'm not in the book". He is referring to the fact that he is not in the phone book, but this is actually an inside joke at Disney, referring to the fact that he was not in the original Winnie the Pooh book.
Howard Morris, who also appeared with Clint Howard in 'Splash' and directed several comedies in the 60's, provided the voice for Gopher.
