It’s all very complex and wyrd (sorry, weird), but it makes for enjoyable reading. Here’s a sample:

Conina is talking about her father, Cohen the Barbarian — “Yes, well, but from him I got sinews you could moor a boat with, reflexes like a snake on a hot tin, a terrible urge to steal things and this dreadful sensation every time I meet someone that I should be throwing a knife through his eye at ninety feet. I can, too,” she added with a trace of pride.
“Gosh.”
“It tends to put men off.”
“Well it would,” said Rincewind weakly.
“I mean, when they find out, it’s very hard to hang on to a boyfriend.”
“Except by the throat, I imagine,” said Rincewind.
“Not what you really need to build up a proper relationship.”
“No, I can see,” said Rincewind. “Still pretty good if you want to be a famous Barbarian thief.”
“But not,” said Conina, “if you want to be a hairdresser.”
“Ah.”
They stared into the mist.
“Really a hairdresser?” said Rincewind.
Conina sighed.
“Not much call for a Barbarian hairdresser, I expect,” said Rincewind. “I mean, no one wants a shampoo and beheading.”
