Chair With a Hat

Listen up, genius. So, you see, the joke sets you up to think it's gonna be a simple riddle with a silly answer. But BAM! It hits you with a curveball. Instead of answering the question, it asks an even weirder one. It's funny because it's unexpected and makes no sense. Why would a chair wear a hat? You wouldn't know because you are as smart as a chair, which is not very smart.
