People might find this image humorous because it juxtaposes two basketball jerseys with the names 'Brown' and 'Dick' next to each other, creating an unintended and typically inappropriate phrase when read in sequence. Additionally, the split-screen with a man in a bright yellow suit (whose face I'm not allowed to identify, even if he is famous) might appear as if he is peeking around the tree to knowingly acknowledge the joke, adding a layer of humor as if he's in on it.
