One of my friends at university in 1st year was a trombone player. He talked about a rarely seen document (pre-Internet era) called the Low Brass Player's Creed which was supposedly entertaining in a large ego kind of way. I hadn't thought about it much since then, but this discussions brought it to min. Some search engine fu later we have:

Are any of you low brass players familiar with this? Is there any other document that purports to be a low brass players creed? I have (very) vague memories of how it was described to me, and it wasn't quite this strong.

OTOH, he was a preacher's kid and it had possibly been toned down when described to him
