 SPOILER: Character Jimmy Gator, a quiz show host, claims that "the  book says, we might be through with the past, but the past aint  through with us." The reference is to the opening sentence of The  Natural History of Nonsense, a book debunking superstitious beliefs  published in 1946 by Doctor Bergen Evans (qv), a professor of  English at Northwestern University. Prof. Evans served as the host  of several TV quiz shows in the 1950s (_"Down You Go" (1951)_ (qv),  _"Its About Time" (1954)_ (qv), and _"Super Ghost" (1952)_ (qv)).  Among many other topics, Evans book discusses the belief that it  sometimes rains frogs, an event that features prominently in the  movie.
