the oblongs are not funny at all, man.
They were back in the day. And what they represented. Everybody down at the bottom of the hill next to the Nuclear power plant was effed up. Everybody at the top of the hill, the rich folks were healthy good looking people.
The oblong family, represented in a way the neutered American family. the father was armless, legless, and virtually held no power in the family structure. The main son, who was a flabby bottomed child who was on every medication known to man represented the over medicated children of today. And the list goes on.
