Comics cannot be read in the same manner as prose; instead, the reader must interpret both art and text, filling in gaps in the action with his or her imagination. While the art freezes a single instant, the text encompasses several seconds. As you read the text, left to right, does your perception of the characters change? As Sean says "This blog is going to pot," is his arm raised, ready to strike? Are Earl's arms flung upward before or after you read his speech balloon? Does the sound effect - "B-oo-oo-nnggg!" - happen at the same time as the pot strikes Earl's face?
Astounding, isn't it, how your mind fills in the gaps?
