Part three of Mr. Kline story in DD. In the verbal snafu department: There is a string of dialogue in the story where DD says, "Who does your dialogue? Jane Austin? Ooops. Hope I haven't insulted anyone's literary tastes." Of course, the irony is that literary sensibilities may have been offended because the author's name is actually spelled "Austen."
