There’s a scene in the Great Muppet Caper, in which Lady Holiday explains to Miss Piggy the backstory for the entire movie.
Miss Piggy: Why are you telling me all this?
Lady Holiday: It’s plot exposition. It has to go somewhere.
After reading my novel (old draft, now discarded) for the first time, my brother’s fiancée asked me where I got the idea.
I had no idea what to say.
