The picture shows a sign with the following text: "SORU SORMAYIN BİLMİYORUM TEŞEKKÜRLER". This is a humorous sign that plays on the common experience of being asked a question that you don't know the answer to. The sign is a tongue-in-cheek way of saying "Don't ask me, I don't know!". The humor comes from the directness and the slightly ironic tone of the message, acknowledging that the person doesn't have an answer but refusing to engage in a conversation about it. It's also funny because it's a very relatable situation that many people can identify with.
