I received this in an email this past week.  Couldn't resist passing along.  Partially because some of it rings true.

How to Play Jazz Sax

A Primer for Beginners

First things first. If you're a white guy, you'll need a stupid hat, the more stupid the better and preferably a beret. Sunglasses are optional, but all the really, really good players wear them, especially indoors. You'll also need some gig shirts. Hawaiians are good, but in a pinch anything with a loud floral pattern is acceptable, as are T shirts from various Jazz clubs and festivals. The good thing about the latter is that you can get them by mail order, so you don't have to go to all the trouble of actually seeing live music. And sandals are an absolute must, even in winter.
