Are we human...directionals?

One of my current favorite songs to spin to is "Human" by The Killers. Other than the fun mellow techno vibe of the music, there are a few reasons I like it. Well, The Killers are from Las Vegas, so that's cool. And, I'm convinced, the lyrics are about sign twirling!
This is the chorus:
Are we human, or are we dancer?
My sign is vital
My hands are cold
And I'm on knees, looking for the answer
Are we human, or are we dancer?
Obviously your sign is vital if you're a human directional. And yes, in chilly weather your hands will get cold. Gloves can make it difficult to hold on to the sign, unless you get some of those Madonna fingerless gloves (but lace is hardly warming anyway!).
The song ponders the classic human conundrum "What is our purpose?" in terms of sign twirlers. On one hand we are Human Directionals, that is, we are to point the way as a sign, that were it not human, would be prohibited from the public walkway. On the other, we are entertainers. We are sign dancers trying to attract attention. Sign twirlers constantly struggle to find a middle ground between these clashing ideologies.
The Killers' new song is a musical exploration of this struggle!
However, according to their website, the lyrics were supposedly inspired by a disparaging comment made by Hunter S. Thompson about how America was raising a generation of dancers. Obviously, though, there is more to it.
