Chevalier Theatre welcomes the comedian/actor duo of Thomas Middleditch (“Silicon Valley,” Godzilla: King of the Monsters”) and Ben Schwartz (“Parks and Recreation,” “House of Lies”), who will perform a completely improvised show. From an audience suggestion, Thomas and Ben create characters, scenes, and story lines off the cuff, not knowing where they’ll end up. No hooks, no gimmicks, just two weirdos making everything up in front of your eyes. Every show is totally different.

Tickets are $29.50 and $49.50 through the Chevalier Theatre website/Ticketmaster. (Few than 110 tickets remain.) Tickets also may be purchased, free of online ordering fees, at the Chevalier Theatre Box Office, which is open on Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show.
