Oh of course some US station is, not surprised after The Killing was adapted.
Some hilarious shows have come out of Australia in recent years, though I'm not sure if their humour always translates for US audiences (I know the USA butchered UK show The Inbetweeners horrible, for example).
Try if you like:
Summer Heights High
A Moody Christmas
Summer Heights High was amusing enough, will have to check the others out.
