I do believe the Geneva Convention specifically mentions torture devices like trombones. It’s right up there with harsh language, unsolicited head baths,  and Taco Bell food, which if I recall correctly is listed under germ warfare.

That video has a style I recognize. There don’t seem to be any credits appended to it, but it sure looks like a video I ran years ago by a guy named Czarek Cwazny. I have no idea why his parents named him after the bug juice I used to spill on the carpet in the living room while watching Star Trek, but he’s a talented feller. If it’s not him, he should sue, or talk angrily, or something.
