Ralph refers to his mother-in-law as "Mammy Yokum". Mammy Yokum was a character in the Li'l Abner comic strip by Al Capp.
One of the rare Honeymooners episodes that ends very downbeat and defeatist, with Ralph not reconciling with Alice, him now having no job, and also being in debt for using counterfeit money to buy a custom-tailored wardrobe he cannot return.
Although credited, Joyce Randolph does not appear in this episode.
