A guy comes home from work to find his front door smashed to splinters. He calls the police. When the cops arrive, they can plainly see that it is a burglary so they ask the home owner what is missing?
The home owner says, well, I've been teaching myself to play the trombone, the only thing missing is my trombone.

You're correct, mag! It is a bad joke. :D

But, I can really identify with it, because in the summer, when I'm practicing the piano late at night, I'll have a neighbor who will call me up and leave a message about how much he thinks the music is melodious, however...

What I've done is to shut the lid on the grand piano and to attach moving blankets to both the bottom and the top of the piano to help to cut down on the sound.

Sounds like this was the same person who stole the violin I had when I was a kid. I would make the dog howl when I played.

Hahahaha
