Many interesting references to The Wizard of Oz in this episode.
They start out in black and white, there is the little dog, a sudden tornado, change to colour; we even have a wicked witch and a good witch in the two sisters. One bars the boy from the table, while the other permits him.
It may be a further stretch, but I think the two men represent two of Dorothy’s companions on the road. The salesman is the scarecrow (friendly but naive), and the oil-seeking man is the tin man.
I believe that the preacher who quickly backed down from making his long-winded prayer is the cowardly lion.
