The San Francisco Improv Fest’s taking their yearly celebration of unscripted comedy – and turning it up to 11! Returning to the historic Eureka Theater, this 11th annual showcase of the best local and national improv troupes is headlined by Upright Citizens Brigade co-founder Matt Besser’s popular improv4humans, Chicago fave Messing With a Friend and married duo Stephnie Weir and Bob Dassie (who go by the hilarious portmanteau of WeirDass). The schedule also includes performances by Best of the Bay winners BATS Improv, musical improvisers HUGE, all-female Bay Area powerhouse troupes Chick Flick and The Right Now, and many more. And since each troupe’s performance is created live in front of the audience, every show is a totally unique – and uniquely hilarious – experience. Please see the full event description for a list of performers.
