The 'Something Is Missing' meme template is a versatile format used to illustrate the sudden realization that a situation, collection, or plan is incomplete. Often associated with the 'Phineas and Ferb' trope where characters notice Perry the Platypus is gone, or various comic strips depicting an artist looking at a blank space, it captures the universal feeling of a glaring omission. It is frequently used by internet users to point out what is lacking in modern culture, sports teams, or personal lives. The humor usually stems from the contrast between a serious search and a trivial or absurd object being the 'missing' piece.
