Put it right after the setup shot, as the cut to the distraction, then follow it with the Woody Woodpecker Laugh to finish the gag, or use You What SpongeBob just before it when the character first notices something odd.
About this sound
This under-a-second voice clip catches James Woods spotting candy and blurting out his delight in a bright, distracted rush. It feels gleefully sidetracked, like a grown man instantly derailed by something sweet and shiny. The line comes from Family Guy, where Woods plays a version of himself who cannot resist a treat.
