In a comic, one way to produce a humorous suspense or simply signal that something doesn't exactly go as expected in a conversation, is to show several copies of the same panel successively. The dialogue may go on and external details may change, but the characters, or at least one of them, will not move an inch. Their position and expression will be a literal copy and paste. This conveys a feeling of stoic disbelief, utter cluelessness or mere indifference from one or more of them, from which Hilarity Ensues. The conversation where this happens usually doesn't go anywhere. In comic strips, the Identical Panel Gag will either precede the punchline or be the punchline itself. In some cases, the entire strip can even be made like this.

`sam sai pef and friends` It’s an art form of its own, the structure and order of a comic, a real science to it, interesting stuff 👌😁
