>You've got to remember that back in those days, in the UK, there were only 2 channels: ITV and BBC. In the 70s came BBC2. We had no choice: it was that or the test card :-)

Ok, I'll grant it might have been a tough choice, but I wouldn't go as far as no choice. Hard to say which way I'd have gone since I wasn't put in that position - North Americans have no such excuse, but I figure I'd have probably watched a couple of episodes of each of them and then finally opted for the test card. It was certainly funnier, and had more emotional range.
