Technically, A Series of Unfortunate Events is a set of kids' books. But there are little jokes and things snuck in that kids won't get and teens and adults will. And that is one of the reasons that they are awesome. Some of the best come from Sunny, who, being a baby, can't talk all that well. So she says things that are supposed to be nonsense at times... But are often real words or names that fit the situation perfectly.

My current favorite is in The Penultimate Peril:

The verdict of the High Court was to take the expression [Justice is blind] literally," said the manager, "so everyone except the judges must cover their eyes before the trial can begin."
"Scalia," Sunny said. She meant something like, "It doesn't seem like the literal interpretation makes any sense," but her siblings did not think it was wise to translate.
