Dear Murray,
How can I become a demonic talking skull like you? You're my role model!

Becoming a demonic skull doesn't just happen, you need to really piss off someone in a high place. After you piss them off they'll find some way or another to curse you into becoming a demonic skeleton, and even then you aren't a skull. Plus you don't have the right frame of mind, I can't be your role model, I need to be your demonic comrade with whom you plan to reign the underworld and ravage the living with your armies from hell! Well anyways, you can't be one, so stop trying. But if you'd like to help me out you could carry me into battle and throw me at the living so that I may scourge the battlefield! (Rolling around just gives me a headache!)
