Professor Girafales is the schoolteacher played by Rubén Aguirre in El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became hugely popular across Latin America and Brazil, where it is known as Chaves. Brazilian meme editors later gave the character a second life online by distorting familiar clips, and bugado edits, in which voices glitch, loop and break apart, became a recognisable style for reaction videos and short-form edits. The humour comes from applying that broken digital treatment to an old television character, keeping him instantly recognisable while making him sound like a malfunction.
