I think one of the best things about Terry Pratchett and Discworld, is that nobody is excluded or discriminated against. It's not racist or sexist, or transphobic. It's not stereotypes. Pratchett punches up, not down. I love Pratchett's view of the world.
This book is incredibly funny, literally laugh out loud at several times.
The hilarious side notes:
page 2;
And instead of getting on with proper science.*
*like finding that bloody butterfly whose flapping wings cause all the storms we've been having lately and getting it to stop.
Another one on page 5:
"somehow no-one had the time to and correct the spelling.*
*Bad spelling can be lethal. For example, the greedy Seriph of Al-Ybi was once cursed by a badly-educated deity and for some days everything he touched turned to Glod, which happened to be the name of a small dwarf from a mountain community hundreds of miles away who found himself magically dragged to the kingdom and relentlessly duplicated. Some two thousand Glods later the spell wore off. These days, the people of Al-Ybi are renowned for being unusually short and bad-tempered.
Conversaion between Granny, Nanny, and Magrat about Magrat wearing pants on pages of 27:
'I don't 'old with it,' said Granny. 'Everyone can see her legs.'
'No, they can't,' said Nanny. 'The reason being, the material is in the way.'
'Yes, but they can see where her legs are,' said Granny Weatherwax.
'That's silly. That's like saying everyone's naked under their clothes,' said Magrat.
'Magrat Garlick, may you be forgiven,' said Granny Weatherwax.
'Well, it's true!'
'I'm not,' said Granny flatly, ' I got three vests on.'
Sadly, there are plenty of fundamentalist religious followers who've made the same argument about women wearing pants, when it's all a thin veil on a way to collar, dominate and control women.
Another side note, this one about the nature of dwarfs and pronouns on page 32:
*Many of the more traditional dwarf tribes have no female pronouns, like 'she' or 'her'. It follows that the courtship of dwarfs is an incredibly tactful affair.
Another interesting, funny and insightful side note about "explorers discovering" a waterfall, on page 41
*Of course, lots of dwarfs, trolls, native people, trappers, hunters and the merely badly lost had discovered it on an almost daily basis for thousands of years. But they weren't explorers and didn't count.
