Learning useful vocabulary
I love this show and as an American I have to rewind every now and then to get the full effect of the colorful terms used - especially by Catherine.
-Referring to the councilman who she arrested as a "teflon twat"
-Being told by the inspector it was "procedure and what we do" and replying "no it's a wank and a toss"
But the best might go to little Ryan when he was mad at Catherine and called her an "old cow bitch wanker", spit some water across the room on that one.
