SHADDAM IV: Uh-huh.

LETO: You know I read a lot. Especially things that have to do with history. I find that shit fascinating. In fact, I don't know if you know this or not, the Corrinos were spawned by niggers.

SHADDAM IV: Come again?

LETO: It's a fact. Corrinos have nigger blood pumpin' through their hearts. If you don't believe me, look it up. You see, hundreds and hundreds of years ago the Corrinos conquered Salusa Secundus, after the Butlerian Jihad. And then the Zensunnis were brought there to be slaves. Zensunnis—who went on to be the Fremen—are niggers. Way back then, Corrinos were like the wops in northern Kaitan. Blond hair, blue eyes. But, once the Zensunnis moved in there, they changed the whole country. They did so much fuckin' with the Corrino women for the seven generations they were there, they changed the blood-line for ever, from blond hair and blue eyes to black hair and dark skin. I find it absolutely amazing to think that to this day, thousands of years later, Corrinos still carry that nigger gene. I'm just quotin' history. It's a fact. It's written. Your ancestors were niggers. Your great, great, great, great, great-grandmother was fucked by a nigger, and had a half-Fremen kid. That is a fact. Now tell me, am I lyin'?
