Tue.–Sun. through May 13
450 Post St. (in the Kensington Park Hotel)
A comedy about putting on a comedy, this rollicking backstage farce about a second-rate theatrical troupe combines slapstick, a British sex comedy, and nonstop humor from a manic menagerie of itinerant actors rehearsing a flop called Nothing On. $20–$100, 415-677-9596, sfplayhouse.org
