Twins are funny and two twins getting hit on the head at the same time (above) are funnier still. Nobody in Goldber's universe stays in center screen very long. The world around funny people is funny too. Weird people are always passing in the foreground and background.
Goldberg's generation knew that suits with tails (above) are funny. Even normal business suit jackets had a high, tight-fitting waist line that flaired out below the waist and had a big center cut in the back...perfect for interesting back shots.
Goldberg was fond of kibbitzers who stood around commenting on other people (above). Sometimes a ridiculous number of kibbitzers and loafers would show up. They'd lean against walls, help themselves to your chewing tobacco, and argue with each other, all the time making sarcastic comments about you.
Notice the twins at the window. Twins with beards are God's gift to cartoonists.
The Olive Oyl head (above) is a great template for funny characters of both sexes. I love little, beady eyes on a ball with a low nose and mouth. Goldberg correctly adds to the effect by giving men suit jackets made with Cliff Sterret-type drapery patterns.
This (above) is from my favorite Goldberg period. He seemed incapable of doing a drawing that was less than hilarious. Nobody in the Goldberg world of that time fit the chairs and vehicles they used. Even their clothes didn't fit. People were always out of sync with their enviornment but they were all so obsessed with what they were doing that they didn't seem to notice.
Goldberg eventually did more normal kinds of strips like the one above, but you get the feeling that he considered them to be a burden.
I wonder if he was influenced by the plague that overtook silent live-action comedies in this period. Even before the invention of sound films the studios began to show disdain for gag shorts. They increasingly turned out comedies that told a story and more or less followed the rules of dramatic story telling. Why the studios chose to commit comedic suicide is beyond my understanding.
