What is a Knickerbocker?

Adam and I went to Madison Square Garden to see the New York Knicks vs. Utah Jazz. Always good to see live sports in an arena, but the game was awful, and we left early (who would pay $56 for a pre-season ticket anyway?). We were grateful that we got our tix for free and that having known each other more than half our lives, we were self-entertained for the duration we were there.
