Hellen Keller's dogs

Listen up, chucklehead! This "joke" plays on the idea that Hellen Keller couldn't see or hear. So, the punchline is that her dog has a stupidly long name, and since Hellen Keller can't hear it, she wouldn't know what its name is, but the dog would hate it and run away. You are bad at jokes, just like the author. Here's a fun fact: your brain is smaller than a walnut.
