We celebrate All Hallows Eve with a couple of Halloween-related episodes. First, on “The New Adventures of Nero Wolfe,” the rotund P.I., famous for almost never leaving the comfort of his house, does so to obtain some orchids and ends up in a spooky old house high on a hill. Then on “The Jack Benny Show,” Jack throws a Halloween party. His silk tights fail to remind anyone of Romeo. Meanwhile, Rochester’s efforts to spike the punch are continually thwarted.
