Two for Improv: Comedians Colin Mochrie and Brad Sherwood, above, will create hilarious and original scenes in their two-man show, 8 p.m. Nov. 21, State Theatre for the Arts, Easton. Known to TV audiences for their work on “Whose Line Is it Anyway?,” Mochrie and Sherwood improvise new material every night from audience suggestions and participation. The show is “interactive” in every sense of the word. It’s a comedic high-wire act, a live version of “Whose Line!” The TV show, “Whose Line Is It Anyway?” returned in summer 2013 to The CW. Season two returned in 2014. A third season has been announced. Although they attempt to keep the show family-friendly, the duo cannot be responsible for audience suggestions. This show is intended for all audiences. Tickets: State Theatre Box Office, 453 Northampton St., Easton; statetheatre.org, 1-800-999-STATE, 610-252-3132
