Great idea for a topic
When I was around 10 years old I took recorder. At the recital while others were playing their pieces I decided to practice my song just not blow. So I had the recorder in my mouth and was moving my fingers for the correct notes when I accidentally breathed through it making a nice loud screech I put it down real fast and looked at my brother who also played the recorder as if he'd done it. Don't think I fooled anyone though
