It's a tale as old as time: Lift, enamored of Cassius, invites him to his elegant wood-paneled office to make an offer he can't refuse, and also to do some blow. Cassius takes the blow, but before Lift can make the offer, Cassius goes searching for a urinal to relieve himself, finding instead the fruits of Lift's efforts at splicing man with horse, which, once Cassius has recovered from his initial horror at the discovery, circles back to Lift's unspoken proposal. The twist's effect is a 50,000 watt jolt to the brain that lasts for the rest of the movie and forces us to reconsider every preceding plot point for the sake of comprehension and personal sanity.
Lift's shindig is Sorry to Bother You's fundamental sequence, where Riley shows us details of a world that's familiar, though fictional; it's a vivid, madcap satire of corporate capitalism and the many layers of American racism, and in directly linking the two, it's painfully obvious that to speak about them separately fails to understand the depth of either's problems. Of course "talking white" would propel Cassius to telemarketing's upper echelons. (Stanfield's white voice comes courtesy of David Cross, amplifying his declarative whiteness for profound comic effect.) In this narrative arc you see the union between America's greatest pastimes: bottomless greed and casually ingrained bigotry.
