Weaver plays Lulu Du Bois, a nymphomaniac who needs sex every 15 minutes but can’t remember what happened yesterday. She’s a classic Durang wacko who beds a minister, a right-wing senator and a guy who maims her in Act I, then becomes a Jesus impersonator in Act III. This intersection of sex, religion, hypocrisy and spiritual emptiness was bracing two decades ago, when Durang first made a splash. But now it’s trite and labored and, worst of all, almost devoid of humor. Even the puns, quips and hysterically inappropriate comments that pepper Durang’s spiciest plays have been replaced by four-letter outbursts and facile jokes about Babylon’s being on Long Island. For those who don’t get Durang’s point about the human condition, he has Weaver whine about ““longing’’ over and over. The rest of us are left just longing to go home.
