Tony the Tiger was introduced by Kellogg's in 1952 as the mascot for Frosted Flakes, voiced for decades by Thurl Ravenscroft. His stretched catchphrase became one of the most quoted lines in advertising, printed on cereal boxes and repeated in commercials for generations. As clips moved to soundboards and short videos, the line escaped its cereal context and became a general meme reaction for approval. Its longevity comes from instant recognition, even for viewers who have never seen the original adverts but know the voice and delivery.
