For sure! I'm an SF-based software engineer who's also on an improv team that did monthly performances in the Before Times.

There are three "big" improv theaters in SF which I know of: Endgames Improv in the Mission, Leela in SoMa, and BATS Improv in the Marina. The show you might've heard of is "Your F'd Up Relationship", which is put on by Endgames Improv's main house team on Fridays at 9 and 10:30. That's a great one to start with. Speaking as an improviser, those performers are especially strong, and the format helps them be consistently funny.

You can also take classes from those theaters, or from a couple other spots, like Thunderbolt Comedy (who actually have a really neat online platform called Pineappl: a web app that's designed specifically for improv, so that performers can simulate being on stage, maintain consistent relative positions to each other, set custom backgrounds, etc. without wrangling any of the messy Zoom stuff like covering up your camera when you're "offscreen".)

Unfortunately the city's comedy scene has taken a massive hit due to the pandemic. I have to imagine that being locked in a crowded room with 50 strangers all laughing is just about the last thing that the city is going to allow to reopen. It seems like Endgames is in financial trouble, since they've put one of their theaters up for rent and the other one is running GoFundMe's. To me, watching Zoom improv really just isn't the same -- really, so much of the improv experience is sharing it with an audience. I really do hope the theaters survive the pandemic so we can have in person shows again when it's safe!

When Sketchfest becomes a thing again, that's improv heaven. My favorite was when UCB did their show where they improv off of an audience member's Facebook feed. And this woman had an old Facebook official pirate theme that changed all the words to pirate slang.

I went to a Secret Improv Society show at Shelton Theater on Sutter in SF. It was hilarious!
