What do you know today that you didn't know yesterday?

[Fireball]

It's page 444, so I'll interject some trivia. I used to work as a mechanic, and I learned a lot about the industry, in general. If you took your vehicle into a Goodyear tire shop, they had a sales pitch called the 4-4-4. Four tires, four shock absorbers and four ball joints (suspension parts on vehicles of that era). They'd prey on young women, and sell them all those parts, which came to a lot of money. My youngest sister fell prey to it, and the mechanic even offered my other sister (who was with her) a ride home, as the car was "considered unsafe". My sister called my mother to come get them instead. My mother was a real spitfire, and went to the tire shop and read them the riot act. Little sis went home without the new tires and all the other shit they tried to hussle on her. I found a tire shop to replace her tires without the extra sales pitch. I ended up buying the car from her, and I did actually replace those parts, years later.
