Martin Harris appeared in the episode, "All About Mormons", where he helps Joseph Smith translate the tablets into the Book of Mormon. He explains it to his wife, Lucy Harris, and she didn't believe him. She hid the original translations so that Joseph Smith could translate the tablets again, thus proving the story. Joseph Smith told Martin that god was angry and that the second translation would be different.
