Put this sting right on the failed attempt itself, before any reaction shot. Lead into it with the dramatic dun dun dun sound effect for a fake-serious buildup, then follow it with the spongebob fail sound effect if the person keeps trying anyway.

This is a roughly six-second brassy trumpet sting played by El Chacal de la Trompeta to stop a performance cold. It feels cheeky and merciless, turning embarrassment into comedy the instant it blasts. The cue comes from Sábado Gigante, the long-running Spanish-language variety show hosted by Don Francisco, where it signalled a singer was out.
