Runaway Stage Productions gets frisky and risky with this raunchy musical comedy. A talented cast runs riot with the innuendo, sex jokes and politically incorrect humor of this grown-up version of Sesame Street. Scott Bolt (in the dual roles of Princeton and closeted investment banker Rod) leads the cast, with Amanda Goldrick (as the virtuous Kate Monster and loose Lucy) and Andy Hyun (as Nicky and Trekkie). But two songs present the show’s big problem: While preaching tolerance, acceptance and avoidance of stereotyping (“Everyone’s a Little Bit Racist”), it takes too much joy in making fun of the Asian character Christmas Eve (“The More You Ruv Someone”). Th, Fr 8 pm; Sa 2 & 8 pm; Su 2 & 7pm. Through 3/31. $18-$25. Black Box Theatre at the West Sacramento Community Center, 1075 W. Capitol Ave. in West Sacramento; (916) 207-1226; www.runawaystage.com.
