Little is known about who first recorded this Dutch open en dicht clip, so its history is mainly online rather than from a film or show. It circulates as a short WhatsApp audio, where the format favours brief, repeatable voice jokes that work without any visual context. The simple contrast and stretched delivery make it easy to forward, reuse and recognise after one listen. It has stayed in use because opening and closing is an everyday action, giving the clip endless low stakes situations to attach to in chats and edits.
