I must confess, the explaination ones are some of my favorite, but thats probably 'cos I love to learn more about the puzzles and mechanics of the world and figure out how they apply. Although my favorite of all time is still the poker lesson. I still claim that its the best simple lesson I've ever seen. *meh* I guess Brion doesn't have anything he needs to explain for the next chapter so the intermissions don't need to be informative. Although I get the impression that we're about to learn quite a bit more in the next chapter about some secret properties of magick, etc.
