• (47:13) "hes got like a iron hat on his head"

Primitive science fiction: Eusa's knowledge is sucked out of his head into a computer. Riddley's people don't seem to have any conception of intelligent machines, and in such a head-centric culture, the idea of having a "No. 2 head" (as opposed to the other "main part" or "little head" that Eusa joked about earlier) would presumably be both fascinating and repellent.
