Put this clip just before the reveal moment in your edit, then follow the actual surprise with the Law and Order Dun Dun for a mock-serious payoff or the DJ Airhorn Sound Button when the reveal is meant to celebrate something.
About this sound
This is a short spoken clip, about four seconds long, of a voice announcing Gordon and building up to a big surprise that never quite arrives in the line itself. That unfinished build gives it a tense, playful feeling, like a drumroll in words, making listeners lean in and wait for whatever reveal is supposed to follow next.
