Paul - I've only skimmed through it, but I'll look forward to returning. It's well researched, enlightening and interesting. I particularly like the analysis of the structure of the gags.

One minor correction, though. I know the rest of the country won't care, but it's of major significance in this tribal corner of North East England. James Bolam, although he seems to go to great lengths not to acknowledge it, is from Sunderland and therefore a Wearsider - not a Tynesider.
