ASSSSCAT is the long-running, show-and-tell version of improv at UCB Theatre, shaped by audience suggestions and built in real time by a rotating cast of comedians. It traces a direct line to New York’s modern improv boom, where UCB helped formalize a scene that fed comedy clubs, TV writers’ rooms, and downtown stages. The format is simple and public: short scenes accumulate into a loose portrait of the room. Its critical strength is restraint, letting patterns and group dynamics do the heavy lifting rather than forcing punchlines.
