La Bruja del 71 is the nickname given to Doña Clotilde in El Chavo del Ocho, the hugely popular Mexican sitcom about life in a shared neighbourhood courtyard. The children call her that because she lives in apartment 71 and they are convinced she is a witch, even though she is really a lonely older neighbour with a dramatic flair. Short clips of the character have travelled far beyond the original broadcasts through memes, reaction videos and Spanish-language soundboards, where the name alone triggers instant recognition for viewers who grew up watching the show.
