What were your favourite things from the first series? Which elements are you going to carry through into the second one?

W: The second series is all new.
M: Yeah, the only things we've kept are Sir Digby Chicken Caesar and there are some Numberwang- ish sketches with a bit of a twist. But I really enjoyed doing the snooker commentators in the first series.
W: BMX Bandit was great.
M: But our feeling was that when you've done the joke, you should move on. And so with the second series we deliberately didn't bring anything back. I really like sketches that just stand alone.

What would you say was your least comfortable moment of filming?

W: I was sitting in a bath of cold baked beans, and it was quite a crisp May morning, and we were in a barn that was basically outside, so I was cold and doing a bit of moaning. And I had quite a long opening monologue, which was one tracking shot, which I kept screwing up. So there's footage in the documentary of me slightly shivering and looking a bit cross.
M: Well I'm always too hot, and Rob's often too cold. And we were doing the Holmes and Watson sketch, which is one of my favourite sketches from the first series. But essentially it turns out that in the Victorian era everyone was too hot the whole time. They were wearing thick layers of woollen suit and tweed and moustaches and hats and this sort of thing. And we were doing quite active, fighty scenes indoors, with lights, on a hot day. And it's fine if you're doing that for 20 minutes, but when it's all day the minutes become like hours and you can't wait until you can take all your clothes off.

And did you?

M: I have since. Between now and then, I have been nude.

Are you tired of the Fry and Laurie comparisons yet?

M: I think Fry and Laurie were brilliant, and I want people to enjoy us for what we do. But I wouldn't exactly fancy our chances in a head-to-head.
W: It's not a comparison that we would necessarily invite. But we think they're great. So it's very flattering I suppose.

Can you see yourself following in Hugh's footsteps and finding fame in the US? They're lapping up British comedy over there.

W: Who knows? But I think we're happy here making British telly. I don't think either of us wants to live in America, but you never know.
