The exact origin of this 'Did you know that' clip is not documented, and it circulates as a generic user-uploaded soundboard sound rather than a quote from a known show or film. Online it functions as a universal setup line for trivia-style content: fact videos, meme edits, reaction clips and short-form posts use it to cue the audience that an interesting detail is about to land. Its staying power comes from that flexibility; any surprising statement sounds bigger when it is introduced like a fun fact.

A short voice clip saying 'Did you know that,' used as a setup line before a surprising fact or trivia reveal in memes, edits and short videos.
This is a short spoken clip built around the phrase 'Did you know that,' delivered like the opening of a fun-fact segment. The voice is clear and upbeat, with a rising lift on 'that' that makes the listener lean in and expect something surprising next. It usually runs just a few seconds, ending on the setup without giving the answer away. Dropped into a video, it works like a verbal drumroll: it signals trivia is coming, adds a playful teacher-like tone, and makes the reveal that follows land harder.
