I like the joke, and I somewhat understand.
If you were doing it as joke, and not doing it to piss people off, I would be all for it. I'm in one of the top marching bands in Michigan, and we still goof around. Most band people have a sense of humor, believe it or not.
Band has a shitty stereotype as it is. Many thanks to movie such as American Pie for making band look completely retarded. In reality, it's nothing like it.
If the band doesn't make fun of you, don't make fun of them.
Thank you very much.
