The exact recording of this clip is not documented, but the phrase itself is one of the most common German-language reaction sounds shared in WhatsApp groups and meme edits. 'Weiß ich nicht' is the everyday shrug answer every German speaker reaches for when a question has no easy reply, which is why the clip works as a universal dodge. German soundboard communities keep it alongside other deadpan reaction lines, and its steady views show it still gets sent whenever someone asks something nobody wants to answer.
