The Sad Guy Happy Guy Bus meme, also known as 'Two Guys on a Bus,' originated from a 2013 illustration by Brazilian artist Genildo Ronchi titled 'As vezes só depende de nós' (Sometimes it only depends on us). The image depicts two men sitting on opposite sides of a bus; one looks out at a dark rock wall in despair, while the other gazes at a beautiful sunlit mountain view with a smile. It became a viral sensation in late 2021 as a relatable metaphor for perspective and the power of a positive attitude, often used to compare how two different people or mindsets react to the exact same circumstances.
