a dialogue bubble in a comic strip that serves less as a medium for conversation or character development and more for the purposes of explaining to the reader what they are to find amusing. it is similar to the idea of “telegraphing” a joke; however, instead of simply making it obvious that the joke is imminent, a buckleybox -n-lyzes the joke itself in order to inform the reader from where the humor is intended to be derived.

it is often -ssociated with a lack of writing apt-tude, in that the writer is unable to artfully craft humor and must, instead, resort to prolonging the punchline to the extent that it is lost in text. in every situation of a buckleybox, it is possible to remove the box entirely while simultaneously improving the quality of the humor.
