I have three favorite fictional names. The first, Candide; the second from the same work, Mr. Pangloss, probably the ideal name for an incurable optimist.
My third favorite name is from a 1960s Richard Brautigan novel: Trout Fishing. One of the reasons I love this name is that the book is titled "Trout Fishing in America". After it was published Brautigan received an invitation to speak at a convention of fly fishermen. He had to explain that his book had nothing to do with trout fishing as such at all.
