Neil Gaiman nicely pointed to this article by Mark Evanier about the lives of the people that play the characters at Disneyland.
I make some snide comment and it prompts a debate. The topic is whether the tiny tots who visit Disneyland really believe that those huge, non-speaking cloth-and-rubber critters are really Sleepy, Grumpy, Bashful, et al...or if they understand that they're just teen-agers in dwarf suits.
One lady who's been listening in on the conversation insists the kids believe. Another eavesdropper insists that no one over the age of three believes that Donald Duck really exists, let alone that he's six feet tall with eye openings in his beak.
Mr. Goofy/Hook is the expert here. He says, "The kids believe I'm Captain Hook the way they believe the Country Bear Jamboree is alive or that the Flight to the Moon ride actually goes to the Moon."
