Silvio Santos was one of Brazil’s most famous television presenters, known for his long-running variety and game shows and his playful way of teasing contestants before they locked in an answer. The question “Você tem certeza?” became one of his recognisable catchphrases, capturing that moment of hesitation before a final decision. Shared widely as a short audio and meme in Brazil, it is still used online to challenge a claim, a guess or a confident statement, especially when the outcome is about to be proved wrong.
