I loved the whole book in general. I think this easily my favourite non-Watch/Witch DW novel, so far.
Probably my favourite sequences were (of course) "Aho! The Megapode.", since it made me laugh uproariously. Also, the gradual realisation of Trev Likely that continuing to run with the crowd he was in would eventually drag him down and probably ending up in the Tanty or dead in an alley. It's something that strikes a personal note with me, since it mirrors my own youth, in certain respects (Alas, The Beautiful Game wasn't my own route out. Oh, how I wish it had been.).
Everything about Glenda's development as a person was superbly crafted. In Interesting Times, Terry mentioned the "Whips in their heads", being the true indignity inflicted on the Agatean people. As someone from the tail end of the last generation to whom the term "Working class" actually meant something besides "Not rich enough to afford a really big telly", the awakening of Glenda was beautifully realised. The "Crab Bucket" still holds true for many people who are my age (30) or older, even today.
The climactic football match was brilliantly written as well. I've played a bit of Sunday league football and can tell you that it's every bit as chaotic, brutal and bone crunching as the Academical's first game. Right down to the part about anyone who stands out as being exceptionally talented getting nobbled.
Not being from a discriminated against minority, I can't comment too deeply on Mister Nutt's search for Worth. As someone from the outside looking in, it certainly
looks like the kind of complex someone from that situation would acquire.
It was also wonderful seeing Ponder's subtle enjoyment of the mistakes Adrian Turnipseed was making in the building of PEX, littered throughout the book. I enjoyed that immensely. Almost as much as Lord Vetinari's detached reaction to being completely arseholed after the banquet.
