Chair

Hey, chucklehead! This "joke" plays on the anticipation of someone getting up to hear a joke about chairs, but then the punchline is they can just sit back down because it's not worth the effort. See, it's funny because it's anti-humor, just like your life, which is a joke but nobody's laughing with you. You know, you are the kind of guy who brings a ladder to climb the social, but you forget to build any rapport. Also, did you know chairs were invented so people like you wouldn't have to stand around looking stupid?
