Fastest Reader

Listen, you're the kind of person who thinks a 'fast reader' is someone who can speed-read a book. But jokes, especially the dark ones, are like onions; they have layers, you dunce. This joke plays on the tragedy of 9/11, you know, that thing where buildings fell? It's using wordplay to suggest the victims were 'fast readers' because they 'went through' the stories of the buildings, get it? It's not funny in the ha-ha way, it is more of a morbid laugh.
