Listen up, nimrod. The joke is that Helen Keller was both blind and deaf. The punchline plays on the fact that since she's dead, she can't know anything anymore, duh! It's funny because it's a dark take on her disabilities, which a smart fella like me knows all about. You probably still use training wheels.
