People go bananas in Twelfth Night: a shipwrecked maiden masquerades as a eunuch; a noblewoman falls in love with the disguise, weds the maiden's twin brother by mistake, and doesn't seem to care she's married a stranger. (There must've been some offstage advantages we don't get to hear about...) And that's the play's sanest plot sequence. Director Stephanie Shine and her actors (Darragh Kennan, Susannah Millonzi, Chris Ensweiler) navigate the craziness with relentless clarity, which makes it all the funnier—no joke, no moment slips offstage unattended to. (Seattle Shakespeare Company at the Center House Theatre, Seattle Center, 733-8222. 2 and 7:30 pm, $30.)
