  6. You gotta put the ducky if you wanna play the saxophone.
    I've spent a lot of time thinking about this one. Does it mean true art requires that we leave security and comfort behind? Or maybe that we must put aside the frivolities of youth to participate in the adult world. I've decided, ultimately, it's literal: The blues saxophone is a two-handed instrument. You can't play it while holding a rubber duck. Ernie.
