Funny sound effects

Four notes falling away, brassy and deflating. It reads as failure instantly, which is why it needs no setup at all.

A thin swoop up and back down in one continuous glide. It exaggerates movement, so it works best against something physically happening on screen.

One taut metallic twang wobbling and settling. Short enough to land on a single frame, which is what makes it a punctuation mark rather than an event.

A round hollow plop with a brief airy tail. Light and clean, so it punctuates without the heaviness a bass hit brings.

Two snare hits and a cymbal. The oldest joke punctuation there is, and it still tells an audience exactly where the laugh goes.

A thin rubbery squeak with air behind it. Absurd rather than clever, which makes it the right choice when the joke is physical.
