The phrase comes from the language of American fast food advertising, where chains stressed that an offer was available only at a local restaurant. Isolated from any actual advert, this recording began circulating online as a standalone meme sound credited to voice actor Roger Craig Smith. Its humour depends on familiarity with those earnest commercials and on hearing such a specific slogan without a product, price or offer attached. Shared on soundboards and in short edits, it has stayed useful as a universal sign off for pizza related jokes and mock promotions.
