Too bad they didn't make it to episode 2. I feel like "they're not just THE emergency services, they're YOUR emergency services" is one of the most British things I can imagine. (I say that as an American, though, so I don't really know what I'm talking about.)
The IT Crowd always impressed me with their set design. I was working as "IT" at the time, and our office was nearly identical to the one in Season 1. We had O'Reilly stickers everywhere. There were an infinite number of desk toys all over the place. We spent 99% of our day screwing around. It just felt so authentic to me at the time, and still does to this day. (Some of that screwing around was legit office stuff, though. Our air conditioner's drainage pipe was blocked, so we rigged up a fish tank pump to pump the water out of it into a giant bucket. We'd then dump that in one of the many floor drains that our office had, because of course our building's hallway had floor drains every 3 feet. The other 1% of the day was screwing around under the guise of helping people. We were the computer support team for the Physics department at the University of Chicago. People who had recently won the Nobel prize would come to us with things like "my hard drive died", and we would just put it in a plastic bag, immerse it in liquid nitrogen, and copy off their files. Worked every single time. Did we ever try copying the files before freezing the thing? Absolutely not. We weren't the scientists, we were a bunch of random idiots trying to help, and we had an unlimited supply of liquid nitrogen in the building.)
