When "The Rye" from season 7 was first broadcast on tv it included the horses gas sound effects, but because people called and wrote how offensive it was it was never again broadcast with the gas sounds. Does the Season 7 set contain the original sound effects or are they deleted because of those party poopers? Haven't purchased it yet, but probably will even if they deleted the sound effects.
Ask yourself, why they would charge full price for a show, on DVD, and want customers to buy it, but delete/censor something that had already been shown on Network television? Now, when you answer that, you'll have your answer.
