My brother and I were talking a few weeks ago, and we came up with something pretty fun that I thought you guys could try. Hum some note, (falsetto stuff works the best for me) and then buzz your lips, losely, so you get a bububububub sound (or whatever you want to call it). Now, get out your tuba, and do the same thing into the mouthpiece. It might take a bit to find the right register, but when you do, I'm sure you'll laugh pretty hard. It's really quite amusing.
