Serious comedy; hilarious drama. The Improv Society's theatrical shows are a raucous blend of improvised sketches and songs: a fast-paced, interactive improvisational revue. Hilarious, bright and completely original, the Improv Society is a San Francisco must-see. The company regularly features guest improvisers. San Francisco's best improvisers, comedians and musicians come join the quick-witted cast in applying their unique creative process to whatever the audience throws their way. Shows end by 11:30. Plenty of time to catch your BART train.
