There's no standardized unit to express how much pain we're feeling. Sure, there's the 1 to 10 scale an emergency room doctor might use, but I think we need something more comprehensive. I think the fundamental unit of pain should be named the Moe, after the stooge.
"Oh, man. My stomach is killing me! I'm feeling 2,000 Moes over here!" Doesn't that sound better than saying, "I really, really hurt"? And if we wanted to get really creative with it, we could call pain medication Moe-phine.
