Years ago, I saw a discussion about a writer who had, allegedly without humorous intent, injected some surprising atmosphere into a story by saying that "moonlight raked the lawn".
The contributors to the discussion all recognised the silliness of the metaphor, and vigorously tried to analyse the nature of this gaffe — without, it must be said, achieving any great insight.
In the process, what became clear is that few people could invent other metaphors that produced the same type of comic effect. I find myself still interested whether there's a concise name for a metaphor with this type of failing. More interesting for me, how can a linguistic trick whose humour is so intuitively understood have so few ready examples?
