The Phantom Tollbooth by Norman Juster

I read this when I was a kid but hadn't revisited it for over 20 years. I basically didn't remember anything about it except for the boy driving around in his car. But Dane discovered it on his bookshelf and read it and was talking about how good it was and wanted me to read it, and this was one I definitely wanted to remember. (Sometimes he wants me to read the most random books and I don't always have the energy.) I really liked re-reading this and it was fun to remember the funny wordplay and puns that make up a lot of the book. I wasn't sure how much of it a kid would understand, but apparently Dane understood enough of it to like it.
