Raddoppiarlo - S4-E3
Character mistake: Deafy says he's a priest in the Mormon church and a member of the Quorum of the Seventy. But he wouldn't be a priest, he'd be an elder or a high priest. There's such a vast difference in the Mormon church between priest and high priest that he wouldn't refer to himself as a priest, even to a non Mormon. Especially since a priest in the Mormon church isn't close to what a layperson thinks of when they hear that word. He also mispronounces the word "Lamamite", even though he's from Utah.
Factual error: The arm on the phonograph is on the wrong side. It should be on the side near the viewer.
