Perhaps you remember too. I had forgotten about the episode titled The Monster of Walnut Grove. Until I started watching it. Then I remembered what an impression it made on me as a kid. In it, Laura sees Nels cut off Mrs. Oleson's head with a sword.
Laura is terrified and tells a few folks, and Nellie and Willie realize she is mistaken (what she actually saw was Nels cutting the head off a mannequin), and take advantage of the situation by terrorizing Laura, in typical Nellie/Willie style. Never fear, though. Laura gets her revenge in the end.
The first time we watched, the twins were so scared they had to come sit on my lap and snuggle. But then once they knew that none of it was real, they were delighted. Now they want to watch nothing else. But the snuggling is still required. After all, it's still one creepy episode.
How about you readers? Do you remember any deliciously scary shows that you loved as a kid?
