Hand vs Blade

Alright, beepo, listen up, you absolute cotton-headed ninny muggins. You think you're so clever, huh? You're out here trying to make a dark joke about your own body. Your hand, which is typically used to interact with the world, is the opposite of your blade, which is used to cause harm. You're saying it's not sharp. You're implying your hand is useless, unlike a blade. That's the punchline, you goof.
