I got SO wrapped up on the page where the Grand High Witch is telling The Witches how to make Formula 86 Delayed Action Mouse-Maker. I read that page like 10 times, because I was picturing the logistics, how messy is would be, would it work, even? 
 OH MY GOD THANKS A LOT, ADULT BRAIN FUCK YOU. 
 Don't worry, once I realized I was doing it I stopped and started just reading for fun, which is why I picked up this book again in the first place. 
 Roald Dahl is so good for children, he trusts them so much and gives them so much credit as readers. I loved how at the end the narrator, now a mouse forever, and his grandmother, talk about death and how they will probably both die soon but isn't that kind of nice. 
 FIVE BUTTCHEEKS!
