Well I have a bad story and a good one...
Well I was swinging around my trumpet for show and my PRECIOUS mouthpiece fell out and landed on the grass, it was unharmed with only a slight scratch...then I put my mouthpiece and trumpet away in the case and the case flung open! Dropping both my horn and my mouthpiece, that mouthpiece has two flat sides on the backbore but my trumpet survived unharmed.
Now a good story ;)
We had a football game against another school and a for some reason we got the scoop on their halftime show music. We really wanted to mess with them so we play their show music, Thriller, right when they were getting on the field.
