UCB’s 20th Anniversary Celebration

The L.A. location of Upright Citizens Brigade—the comedy troupe co-founded by Amy Poehler in New York in the ’90s—is turning 20, and celebrating by teaming up with the World’s Greatest Improv School, the Pack Theater and the Groundlings for a a day-long marathon of shows, workshops, panels and more. Prices range from free (for shows at the adjoining Annex and a Simpsons trivia competition) to $50 for a beginner-friendly clowning workshop. Topping off the birthday programming will be a performance of UCB’s flagship improv show, ASSSSCAT, where improvisers turn an often-recognizable guest monologist’s suggestions into a sketch, followed by the grand finale of a “Cagematch” battle of improv teams.
