Creators use this kind of closing theme online as a borrowed television convention, turning an ordinary ending into a staged sign-off. The joke relies on shared memory of late-night and daytime shows where music over credits meant the conversation was finished, guests were waving and the host was moving on. Posted as a standalone clip, it became handy for edits that need a clean, funny ending without recording an outro, and it still works for reaction videos, sketches and livestream recaps where timing matters more than a long fade out.
