Bart burns the book Johnny Tremaine, but on the episode "Whacking Day," he read the entire book and liked it.
Skinner's line while Bart is burning books is, "Not Huck Finn! I spent hours crossing out the sass-back!", but in the closed captioning, it reads, "Oh, now you're just burning innocent linoleum. What did it ever do to you?". (On Disney+ the CC says the right thing) It is Possible the cc people were given an earlier copy of the script and the line was changed before it aired.

Lisa is not present in most of the school scenes, such as in the cafeteria or when the kids rebel against Skinner. She reappears when the kids are going to sleep. It is unlikely that she left the room since Skinner locked the doors.
