Put this clip at the very start of the edit as the setup, do the reveal on the cut, then follow it with the bruh soundboard button for the stunned reaction and the emotional damage sound button if the victim needs a bigger payoff.
About this sound
This is a 2.3-second voice clip of the Joker delivering his calm setup line about making a pencil disappear, spoken flatly with no music or effects behind it. It feels tense and darkly funny, because the polite magic-trick wording promises something harmless while his tone hints at a threat. It comes from The Dark Knight.
