I'm not writing a novel, but there's a snippet from the script of chapter two of my comic that I thought was hilarious:
Koreal (grinding something in a mortar and pestle): Tonight, you get to see something that no wizard has attempted in tens of thousands of years.
Girl (grin turns more knowing): Getting laid without launching into a half-hour lecture about magic?
Koreal (mild annoyance, dumping dust into flask): Har har. It’s still going to be impressive.
(For context, the MC (Koreal) is about to attempt some very dangerous and very illegal magic, and his choice of location to do so is a local brothel, because no one looks that closely at what people are up to there, and the ladies will happily deny knowing anything for a bit more coin.)
