"[Taking Jonnie to a library] When we attacked your planet, all your soldiers and all their advanced technology could only put up a measly nine-minute fight before they were exterminated, which is why man is an endangered species. Everything you humans knew is here, and you can look at anything you want, because there is nothing that will help you."
