Thor's Hour Of Thunder

From the Wikipedia page: The series, described as "a Twilight Zone for kids", centers on the kind of myths and legends that are told as scary campfire or bedtime stories. Every episode always starts with and finishes with the phrase: "This is a true story, and it happened to a friend of a friend of mine." and "Just because they never happened, doesn't mean they ain't true."  Tune in THORsday for a special bonus episode!
