The phrase huff and puff comes from the Big Bad Wolf's threat in the Three Little Pigs fairy tale, I'll huff and I'll puff and I'll blow your house down, a line reused in countless cartoons, stage plays, and children's recordings. The Casper reference in the title points to the friendly ghost character, though the exact source of this thirteen-second recording is not documented. Online it circulates as a user-uploaded soundboard clip, kept alive because the wolf-and-pigs joke is instantly recognizable and works for any blow-away gag.
