How does the comic mind work? Where does the funny come from? These and many other vital questions get answered every time Set List comes to town. It works like this: Some of the best comics on the scene are supplied with their “set list” — the topics they’ll cover — when they arrive on stage. Since these lists are conceived by the audience, what ensues is almost completely improvised and, therefore, doubly astonishing, impressive and enlightening. If you want laughs and erudition, “Set List” is one of the best and truest shows you’ll ever see.
