Check out Adult Swim on Cartoon Network (not sure if you get that) if you want dark, offensive comedy. Plus there is Archer, Weeds, It's Always Sunny in Philadelphia, Louie, and even though it's technically a drama Breaking Bad has it's dark comedy moments (as with Dexter). Those are just off the top of my head to go along with others mentioned like South Park.k-ossuburb said:Okay, some American comedy shows are good, however I would point out that not a lot of them seem to take very many risks and the ones that do are often ones that the BBC or Channel 4 sold to them.
When I say "risk" I mean tackling on dark humour or exploring sensitive subjects.
South Park and Family Guy seem to do this pretty well, but other than that there aren't a lot of others that try to take on this level of dark humour.
You can even go further back to older shows like MASH, All in the Family, Titus, older Simpsons episodes, Arrested Development, etc. The list is pretty long.
