A Million Random Numbers
So once you get past the initial, "what a stupid book" impression, I'll tell you that once upon a time, when there were no computers, people needed random numbers generated for experiments and shit. So they actually looked in a book to get those numbers.
Anyway, we have computers now. So it's time to go back to sarcastically making fun of how useless this book is.
