Rabbi Marshak
Larry pleads with Rabbi Marshak's secretary to be seen by him. She slides open a wooden door, walks 30 yards to his desk, talks to the Rabbi, walks back, slides the wooden door shut and sits down before telling Larry that the Rabbi is busy. The imagery creates suspense for the audience as we are unsure as to whether the Rabbi has agreed to meet with Larry or not from his lack of movement and seeing the secretary go through the entire action of walking in and out of the room creates comedy through the visual imagery as it hits on the absurdity that is the contrast between Larry's high-energy pleading to the secretary and Rabbi moving like turtles.
The Uncertainty Principle
Larry is dreaming and in his dream he breaks down the Uncertainty Principle that through mathematics he is able to break down the reality that you can't ever really know what is going on. We watch as Larry feverishly writes out the theorem as he speaks it in a close up shot of his hand. The imagery cuts away to a wide of Larry in a full classroom and a chalkboard 3/4 the size of the frame filled with math behind him. This cut from close up to wide helps to land the joke, and the silence of everyone in the classroom adds to the value of the comedy created from the imagery with the dialogue.
Junior Rabbi
We watch as the Junior Rabbi explains to Larry that he needs a new perspective, and he does so by giving a long-winded, albeit passionate, speech about it as he looks out into the parking lot to explain seeing things with fresh eyes before returning to his seat. This is when Larry explains his wife is already with another man and wants a divorce. The imagery shows the contrast of someone with less life experience attempting to counsel someone through an event they've never had happened to them. The Rabbi looks full of vigor and encouragement, until he realizes he can't solve Larry's problem.
Dead Man Knocking
We watch in the opening scene as a husband tells his wife that he met a man that helped him put his wheel back on his cart. Turns out the man has been dead for three years. We watch as the camera pans to the door after we hear a knock. The pan shows us the fear mounting up. When the wife uses the ice pick she's been cracking the ice with during her husband's explanation to stab the ghostly man, we see how the Coens set up the stabbing in the moments just before.
