Chaves, known in Spanish as El Chavo del Ocho, is a Mexican sitcom created by Roberto Gómez Bolaños that became a cultural phenomenon in Brazil through its Portuguese dub, where Don Ramón is Seu Madruga. The Velho do Saco is a separate Brazilian folk figure, a mysterious old man said to carry children away in a sack. Brazilian internet culture brought the two together, turning Seu Madruga into the face of that childhood scare. The clip now circulates mainly as a short meme sound for jokes, pranks and nostalgic edits.
