Place it at the end of a short gag, after the setup and just before the reaction shot, so the payoff closes the scene. Pair it first with a single duck quack for the setup, then follow it with a sad trombone or a crowd laugh to stretch the joke without repeating the same gag twice.

This four-second clip pairs three sharp duck quacks with a bright trumpet blast, the quacks setting up a joke and the trumpet landing like a comic fanfare. It feels silly and sudden, turning a plain animal noise into a small celebration. The contrast between the waddling quacks and the brassy finish is what makes it stick in the listener's head.
