A very good editor once told me, "when you write a book, there will be one part that you love. Rip it out and burn it. " Quite often, writers will put their work through pretzle like contortions just to put in one little bit, destroying an otherwise fantastic work. Issac Asimov structured the totality of Fantastic Voyage II around one painful pun at the end. With my twisted and somewhat unfortunate sense of humor, I can respect that.
