It’s amazing to me you can say shit and asshole on basic cable now.
You can say anything on basic cable, it’s not FCC-regulated. It’s Always Sunny aired two episodes with uncensored “fucks,” one of which also included uncensored C-, N-, and F-words (the other F-word). Taboo was aired in the US on FX completely uncensored, with multiple “fucks” and worse in every episode, and Mr. Robot airs uncensored episodes now and again, too.
On cable, it’s all about what the advertisers are okay with. If you can get enough advertisers to fill out your hour or half hour without censoring anything, you’re good to go. No FCC fines or anything involved.
