“The Underpants” (Kenner)

Through Feb. 6, at Rivertown Repertory Theatre, 325 Minor St., (504) 468-7221. Steve Martin brings his comic genius and sophisticated literary style to Carl Sternheim’s classic 1910 farce. Theobald Maske has an unusual problem – his wife’s underpants won’t stay on. Mortified, Theo swears to keep her at home until she can find some less unruly undies. Amid this chaos he’s trying to rent a room in their flat. The prospective lodgers have some underlying surprises of their own. Directed by Dane Rhodes.
