"You stole the corn! It’s your father! It’s him!"

By “corn” he means garmonbozia: “doesn’t it look just like creamed corn?” Bob kept the garmonbozia from Mike (the one-armed man); garmonbozia is something like the residue of suffering in humans. Bob was supposed to share it. As I recall. It’s a complex mythos.
