But it's funny how some episodes never seem to come back. I keep thinking of the one in Stoke Poges - I used to drive past it regularly which brought it to mind - and I have never seen that one repeated (beyond, perhaps, the first repeat).
Of course, sad thought I might be, am not quite sad enough to spend time poring over More4 or E4 schedules! But some of the others seem to have been on dozens of times - if you flick through channels it is *always* one you saw in full ages ago, never the one you missed or someone rang half-way through and you didn't see the end...
