9. Comedy Central agreed to air the episode “It Hits the Fan” only after the creators decided to use the word “shit” 200 times instead of a few times. It was because they felt the standards of profanity have changed among viewers and “no one cares anymore” even if a character swore.
The executives at Comedy Central also felt that the amount of profanity was justified considering the context of the episode and decided to air it uncensored. Despite all the significant amount of profanity present in the show, the number of times the word “shit” was used in the episode did not stir much controversy.(source)

Before the episode was released the association expressed concern over the portrayal of people with Tourette syndrome and issued a press release saying so. However, their fears were proven to be wrong and they later conceded that the episode provided accurate facts about the syndrome to the public.(source)
