When Sonny Gets Blue - S1.E11

Maggie needs to ""let her monkey out."" An opportunity arises, when everyone is attending the wedding of Sonny's ex-girlfriend. She agrees to accompany Sonny this event, when she he insists he must attend to obtain closure. The event almost goes off as planned (at one point Sonny introduces Maggie as his fiancé and Miss Nude World) until Maggie says something which re-ignites the old flame between Sonny and his old ex-girlfriend, the ex-bride.
