Chaves is the Brazilian Portuguese version of El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became a long-running favorite in Brazil.

This sente-se, tirou zero moment survives online as a short reaction audio, shared in edits, chats and soundboards whenever someone gives a hopeless answer or earns an unmistakable fail.
