“Desperate Housewives” extends the costume craziness to Sunday (Nov. 4 at 9 p.m. on ABC) as the neighborhood Halloween party offers an unexpected delivery. Sneek some peeks at the trick-or-treat here. [Above: Marcia Cross and Kyle MacLachlan in ABC photo by Ron Tom.]
Tune in an hour earlier to catch the annual “Treehouse of Horror” installment of “The Simpsons,” at 8 p.m. on Fox.
