Have you tried turning it on and off again?
That is obviously the most famous line from The IT Crowd. But it is not in this quiz, because multiple characters say it. Same with "Did you see that ludicrous display last night?" and "The thing about Arsenal is they always try to walk it in".
They're great lines, though.
The IT Crowd was the sitcom that launched the careers of Richard Ayoade, Chris O'Dowd and Katherine Parkinson. And while Matt Berry was already known to comedy nerds, it gave us a lot more Matt Berry, which is always a good thing.
Anyway, here is a quiz where you have to match The IT Crowd quote with the character who said it.
