How does the impoverished Dangerfield secure food for O'Keefe and himself?

O'Keefe comes to visit Dangerfield's rattletrap country house on the edge of a steep cliff. Dangerfield chops up a blue blanket with an ax to make a scarf in Trinity's colors, so he can go to the store and get credit on the strength of his college and his good English accent. He gets liquor, ham, cheese, and a chicken.
