Glamour Profession, like many Steely Dan songs, tells a great, twisted story - filled with metaphors and suggestive lyrics. This one paints a great picture of drug culture in L.A., e.g. "local boys will spend a quarter, just to shine the silver bowl." I'm not sure what that is to this day, but it sounds drug-related. Right?

Update: There's a good write-up on these lyrics here. It all makes perfect sense now! http://songmeanings.com/songs/view/3530822107858654303/
