Shared on soundboards as it goes ding when there's stuff, the clip built its following on the usefulness of the phrase rather than a known scene or character. The wording is easy to quote, search and drop into unrelated footage, so it spread through meme edits, gaming videos and reaction posts where a machine, till or scanner needed a voice. Its spelling is often typed with their's instead of there's, which has become part of how people find it, and the short length keeps it handy for quick punchlines.
