Allow Ben to for the last day of school to wear tubas and other brass instruments all over him for 7th period. If he does it on the senior last day then he can't get in trouble. Class of 2020 had wanted to do no masks for there last day and figured they can't get in trouble for it. 

It would be very fun to have him do it. He's smart and can figured out how to do it. After all he is the brass captain and he heads the sacrifice.
