That episode scared the fuck out of me as a kid for some reason. But I think I now know why. It's not like the other Courage episodes that involved supernatural elements. This one seemed real, like this could actually happen to someone. After all, there are cases like this such as one where a child was beaten to death for misspelling a word. I think it's also why The Hunchback of Notre Dame still frightens me, because there have been tons of people throughout history just like Frollo who can be vile, cruel, and pure evil without having any magical supernatural powers.
But the ending message is nice and it's important to know. : )

Best show and a great message. Though this show freaked me out as a kid I still love it.

That inexplicable bathtub fish and music are the perfect pickmeup.
