Cadets '02-Towards the end of the opener (New York, New York I think, correct me if I'm wrong) a contra player falls during a pretty fast back march and seamlessly runs back into the set as if it were planned.
BD '05- while marching off the field the second tenor player falls and the entire corps just moves over and keeps on marching like it never happened.
another Cadets (I think '02, could be '01) at one point the multi-cam zooms in on the pit and they wink at the camera.
Cavies '02- yes, they loosened their valve caps to make that section more audible and so they wouldn't have to push them down as hard so there would be less stress on the horn.
BD '06- Not real "miniscule" but interestind never the less- right after the tenor and snare solos before the jazz section, they chant "sleep with fish" and another thing that I can't figure out.
