Place this clip immediately after the visual punchline, not before it, so the reaction follows the reveal. Start the sequence with the wrong answer game show sound for a failed attempt, follow with this laughter, then finish with the Nelson Ha Ha sound for a second punchline tag.

This clip is nearly eleven seconds of sustained human laughter with no spoken words, just one voice laughing continuously. It feels gleefully over the top, turning a small embarrassment into something that sounds hilariously huge and making the listener want to laugh along even when nothing that funny actually happened.
