Indirect breach of the fourth wall at the end of the movie "Fight Club". When the plot comes around to the opening scene again after two hours of flashback, the Narrator (Edward Norton) states he "still hasn't anything to say", and Tyler Durden(Brad Pitt) refers to this as "flashback humour".
Any other definitions for flashback humour?
