I'm sure I started a thread about this sitcom before, but I can't find it now, so here we go again:
Does anyone remember The Estate Agents?
It was broadcast in February 2002 on Channel 4 at a late timeslot (11pm-ish). It followed the fortunes of 3 estate agents in London. A pilot episode was broadcast as part of a 'Comedy Lab' series.
There was only one series made unfortunately, but it's funny!
I've recently acquired the whole series and it's certainly worth a watch. I think it's on 4OD, or at least it was. So check it out.
