Mule

A few years ago when I got done busking in Chicago I was talking to a grizzled veteran of musician who we affectionately referred to as Crazy Uncle Ken.  I told him that it was a great busking day, as far as they go, where people got into what I was playing and it didn't feel like I was a nuisance. He listened kindly, said that it was great I had good experience, and then said; "Be your own cake"
