Put it at the very start of the edit to set up the segment, then cut straight to the main footage and follow the reveal with a game show buzzer for a comic verdict, or with emotional damage when the joke is a personal fail.
About this sound
This ten-second opening sting has the polished tone of a classic Thai television broadcast, built around a short formal cue that introduces a segment. It feels thoughtful and deliberately earnest, like the start of an informative programme, which makes a sudden joke land harder. The clip comes from Krajok Hok Dan, the Thai programme whose name means Six-Sided Mirror.
