“The Trash King” is a live comedy event currently running at UCB Theatre, staged in the close quarters where New York’s improv and sketch traditions have long been tested in public. The premise turns on status and discard: who gets valued, who gets thrown out, and who ends up in charge of the leftovers. It plays like a small-scale civic fable, using jokes to track the social economy of the city. In a venue with real institutional weight in NYC comedy, that framing lands with unusual clarity.
