Watch for an unintentionally hilarious moment near the end of the episode, when Almanzo punches Perley Day and knocks him down. There is a very loud (and obviously fake) punching sound, and Perley Day just kind of falls slowly and gracefully to the ground. If Almanzo really did hit him that hard, there's no way he would have gone down at such a slow speed. Also, Perley Day would have had to be bleeding, which he clearly wasn't. More effective rehearsing would have at least ensured that the actual fall looked realistic.
