Southwest Airlines, where's bags fly free and heads don't fly at all

I'm just dying to see where this story is heading (pun intended). For one thing, I had no idea there was any market - "underground", above ground or at ground level - for human heads. Then there's the mention that some of the heads were not "whole" (Exactly what part of the head was being shipped?). And, if you stumbled across a listing for company calling itself "JLS Consulting LLC," I'd be willing to bet you wouldn't automatically jump to the conclusion that their business was transporting human heads across state lines for any kind of purpose. Finally, there's the statement that JLS founder Jance Hepler "works with human specimens to produce educational courses." What exactly does that mean?
