I l.o.v.e.d. that show. I can't say any specific moment because I don't have great long term memory and this is something I watched years ago, but I know I liked any scene with Steve Carell. It's enough for him to make a silly face and I'm all over my floor. I like him so much!
The US version irritates me, but I know at least part of that is that the first series or two was pretty much the British version recreated and I'd rather just see the original.
However, in terms of mockumentary being brought up to date, I've just finished binge watching the sublimely and marvellously wonderful People Just Do Nothing.
