Keke Palmer, the American actress and singer, became a lasting meme presence after her 2019 Vanity Fair lie detector interview produced several viral reaction clips. Short audios of her laughing spread separately on TikTok, YouTube and soundboards, detached from any single interview and reused as a universal laugh track. Editors keep returning to it because her laugh is distinctive, warm and instantly readable even without video, making it useful for comedy edits, reaction posts and celebratory moments years after the original clips first circulated online.
