I've been looking through here and, the ideas are quite frankly hilarious xd but, some of them seem like they might work a little too well, if you know what I mean... Anyway, I, myself don't particularly try to tip our BD's off...maybe a little annoyance here and there but all in fun... If I have to be honest, I think the main thing that annoys BD's the most is wasting their time, like talking and just doing other things to draw attention away from the piece.. After all, BD's are teachers and, we all know how teachers are when their class is interrupted, and not only that but, for band classes, there is a limited amount of time and, music takes awhile to perfect... Talking during rests or just being overly obnoxious works too though... wink rolleyes
