@usweekly: Jim Parsons may have a bit of theatrical whiplash going from #OurTown to #Titanique, but the actor told Us the campy Broadway musical is the most fun he's ever had on a show. As Ruth Dewitt Bukater — a.k.a. Rose's mom — in the #Titanic parody, Parsons returns to a female role, which he tells Us feels "heavenly."
