So I had some clothespins loose in my trumpet case for clipping sheet music, and well, I'm not putting them in there loose again.

When I took out my trumpet for the second time this evening to play it, I heard a rattling. I turned it around and looked down the bell and didn't see anything. Then, I turned it back around and shook it real hard and a clothespin fell out of the bell. I don't know how long it was in there...

Well, I guess I learned my lesson...
