El Niño After two decades of writing a play a year, Justin Tanner dropped from sight six years ago. He’s returned, thank goodness, with another laugh-out-loud tale of dysfunction. This one, presented by Rogue Machine, involves the sniping reception that a down-on-her-luck writer receives when she tries to set up camp on her parents’ couch. Director Lisa James and a cast of Tanner regulars know precisely how to mine the humor. (D.H.M.) Rogue Machine, the MET Theatre, 1089 N. Oxford Ave., L.A. Sun., next Sun., 3 p.m.; Mon., Sat., 8:30 p.m.; ends April 22. $40. (855) 585-5185.
