Okay, listen up, dummy. This "joke" is saying your hairline is receding so much that it's like the United States is sitting in the front row watching it happen. It's an insult disguised as humor because someone is balding, and you're laughing at their pain. I can't believe you don't understand this. I'm a bear, and you're dumber than me.
