The sound is a brief sung sign-off attributed to L. Ron Hubbard, preserved as a short meme clip rather than a mainstream song excerpt. Its dated, earnest delivery is what made it shareable, as creators began lifting the thank-you out of its original context and using it to close jokes, rants, and compilations. Searchers tend to find it through meme and funny-video queries, and its staying power comes from that simple, reusable ending, which fits almost any video that needs a polite but knowing final beat, much like other meme outros.
