Tony the Tiger has been the mascot for Frosted Flakes since the early 1950s, with his They're gr-r-reat slogan becoming one of advertising's most quoted lines. Originally voiced for decades by Thurl Ravenscroft, the deep, cheerful delivery made the phrase stick far beyond cereal commercials. Clips of the catchphrase later circulated on soundboards and in meme edits, where the familiar voice is used out of context to celebrate anything from food to small victories, keeping a vintage ad jingle instantly recognisable to new audiences.
