Okay, it’s clearly not a CIDU because there’s no doubt what the joke is.
But this is sooooo familiar. But I don’t know from where, exactly. This is thus a Comic Whose Familiarity I Can’t Pin Down.
I think I’m thinking of a classic (or at least “very old”) bit by a comedy sketch group, like maybe Second City or The Groundlings or maybe even Nichols and May. Can anybody ID a sketch using this idea or pattern?
That is: a dialogue in which the actually uttered words are descriptions of the place in the structure of the scene occupied by the character’s turn or line; or description of the tone and effect of a line that would go there; or some similar meta-level description in place of the expected base-level line of dialogue.
Also, can you make a short and snappy name for the trope? And more examples, in any genre?
GoComics commenter “The Brooklyn Accent” posted a link to the song clip below, “Title of the Song” by Da Vinci’s Notebook, which does some of the same things and probably belongs within the same trope.
