The Ticket that Exploded
by WilliamBurroughs

*Taking Touchstones's word for it as to the author of this peculiar title: one of the few that ever drove me away from a book. It may not be a metaphor, for alll I know, but if not, then I don't know what it is.
The Hemingway and Rolvaag titles are, i assume, metaphorical, though the source of each of them (Bible: Genesis, and John Donne were speaking perfectly straightforwardly.

Metaphors in titles aren't as easy to think of, as I would have thought. It struck me that Shakespeare, Milton, Dickens, George Eliot, and Updike never used a metaphor in a title. (Correct me, if I've forgotten one.)
