David Mitchell and Robert Webb have always "clicked" as a comedy double act.

The 46-year-old actor and Robert, 48, started working together during their student days, and even though their first-ever performance was chaotic, it still went "very well".
David - who studied at Cambridge University - said: "When we first did a show together as students we were horrendously ill prepared.
"We’d written a script but we hadn’t learned it and we were sort of winging it. But it went very well, albeit in front of p***** students but it went well, and we both felt there was something about performing together that clicked and we had the foresight to realise that, as you don’t know when you’re that age, this isn’t something you’re going to stumble across every day.
"That there was something serendipitous about this, and it’s worth looking after it and persevering."
Robert also feels that they've developed a strong chemistry over the years.
He told NME magazine: "It feels like when you’re on stage I’ve got a pretty good idea of what David’s going to be doing without looking at him and vice versa.
"Part of it is just the sheer weight of years but also I think there was something there right at the start."
Despite this, Robert admitted he's not as witty as his comedy partner.
The actor - who is best known for starring alongside David in 'Peep Show' - said: "It’s perfectly alright to me to come second to David Mitchell in a witty contest!
"I was reading a book about introverts and there’s such a thing as an introvert who pretends to be an extrovert and I wonder if I’m one of those.
"I do find myself on panel shows going: ‘This is a really good episode of 'Have I Got News For You - Oh f***, I haven’t said anything for 45 minutes!’ Then they don’t ask again, and that’s fine."
