If you've ever encountered American TV, you'll know that there's a significant lack of swearing even post-watershed. Thanks to the FCC, TV shows and characters are mostly reduced to 'Goshing' and 'Darning' their way through even the most insane of plots, with everything beyond bitch mostly off-limits (unless you're watching pay-per-view channels like HBO who can basically do whatever they want. Exhibit A: Everything in Game of Thrones.).
So what happens when one of the networks wants to screen a movie with particularly coarse language, say for instance Samuel L. Jackson's magnificently sweary Snakes On A Plane? This.
