Carlos Alberto de Nóbrega has hosted the Brazilian comedy show A Praça É Nossa on SBT since 1987, sitting on a park bench while comedians join him for sketches. His distinctive laugh became part of his on-screen persona over decades on television. Short clips of that laugh later spread online in Brazil through YouTube compilations, WhatsApp audios and meme edits, detached from any specific episode. Because Brazilians instantly associate the sound with classic TV comedy, creators still reuse it as a nostalgic shorthand for finding something funny.
