Place this clip after the line or visual gag you want to underline, not before it, so the reaction carries the beat. For a cartoon laugh-off sequence, follow it with the Woody Woodpecker Laugh and then return to your main audio.
About this sound
This clip is Peter Griffin's distinctive laugh, a roughly 13-second stretch of high, wheezing giggles that keep restarting as he loses control. It feels gleefully stupid and infectious, turning even a weak joke into the funny part. It comes from Family Guy, the animated sitcom where he is the lead character.
