Place it as the full payoff after your fake intro, not as background, then follow the reveal with a bruh reaction for the victim's response and close the sequence with a meme button hit to reset the joke before moving on.
About this sound
This 17-second clip is the chorus of Rick Astley's Never Gonna Give You Up, with his earnest baritone promising he will never let you down. It feels instantly cheeky and nostalgic, turning any reveal into a playful betrayal. The song became the bait in the rickroll prank, where a promised link leads here instead.
