Everybody knows Scuba is actually an acronym. Self Contained Underwater Breathing Apparatus. But a Tuba could also be like Scuba except it's a TERRIBLE underwater breathing apparatus.
@ColesStreetPothole I did do a music appreciation class and we had questions about Napoleon and Sousa. One of the questions was who stormed Vienna and when the answer was "Napoleon" she went "Ah no way I thought it was Sousa". So now I have this image to Sousa laying siege to Vienna with Trombones and Tubas. I could see it.
