Seattle's longest-running show, Unexpected Productions' Theatresports is among the best improv the Northwest has to offer. At Theatresports, teams of improvisational actors use their quick wits to create scenes on the spot, based entirely on audience suggestions. A panel of judges -- sometimes including guest celebrities -- then weighs in on which team is the funniest. Be prepared with clever suggestions to throw out, because the two most valuable audience ideas win prizes. The Seattle Times theater critic Misha Berson called Theatresports "the most polished improv troupe in the city."
