The laugh comes from African Diary, a Goofy cartoon released in 1945, where Goofy's adventures provide the comic setting for this brief vocal reaction. It later entered stock sound libraries as a man laughing track that becomes hilarious toward the end, which helped editors find and reuse it outside the original cartoon. Because the clip is less than a second long, it works as a quick reaction sound in short videos and memes, where the sudden change from restraint to delight reads instantly even without context.
