Carlos Alberto de Nóbrega is a veteran Brazilian television presenter best known for hosting the long-running comedy show A Praça é Nossa, where his warm, infectious laugh became part of his on-screen persona. Clips of that laugh circulated widely through Brazilian social media, messaging groups and meme pages, often detached from the original broadcast and reused as a standalone reaction. It endures because it is immediately recognisable, unmistakably human and versatile, signalling amusement without needing any words or explanation.
