Abbott Elementary's newest Halloween episode shows Barbara on a mission to make sure the students have a good time - but don't break any laws. In Us Weekly's exclusive first look at the Wednesday, October 29, episode of the hit ABC sitcom, Barbara (Sheryl Lee Ralph) asks the kids about their plans for Halloween. The students, however, think they are "too old" for trick-or-treating and instead have other plans that include TP-ing houses, egging apartments and taking part in ding-dong ditch.
