Do not fill this in!==Behind the Scenes== Since his debut in season 2's "[[Gnomes]]", the voice of Richard Tweak has been provided by series co-creator Trey Parker, who uses a voice with only a slightly higher pitch than his normal speaking voice. Mr. Tweak also had a slower, calmer tone in some of his early appearances, similar to his wife. While father and son characters are often voiced by the same actor, Tweek is instead voiced by series co-creator Matt Stone.
