Want to feel like you've really accomplished something today? Watch this four-minute video and you'll suddenly know the endings to 50 books, ranging from War and Peace and A Wrinkle in Time to the entire Harry Potter series and a random Baby-sitter's Club book. I promise you — you will feel exhausted by the end. Maybe not I-just-devoured-50-classics-in-one-sitting exhausted, but definitely I-think-denouement-is-bleeding-from-my-ears exhausted. These guys also do horror-movie spoilers, reality spoilers, Disney spoilers ... basically, they are out to spoil every aspect of your life. Isn't it great?
