I am quite certain that the episode I am looking for was a part of Rod Serling's "Night Gallery." However, after having looked at several online guides for N.G. I have not found the episode in question. What I remember of the episode: an EVIL little boy who has dome pretty awful things (with fatal consequences). He decides to frame his teacher by putting a razor-blade into an apple and then blaming said teacher. The teacher, in question, gets fired from her position. I seem to remember that she is trying to warn others about this child. It's not much to go on but that's all I can remember. This episode is from the early 70's. Any clues/tips would be greatly appreciated.
