Louiseitis, the whole point of this strip is that astrology is bunkum, not to be accurate about it. Asok may or may not be a "Scorpio" and it wouldn't matter to the humour of the strip.
Homeopathy and astrology getting played up in the same strip. He hurt the pointy hair guys feelings. Perfect.
I think that the sign you were born under tells less about you than some people give credence. I'm an Aries raised by an abusive alcoholic and a sociopath. I sleep on my stomach "free fall position" (aggressive) and find that I have always had little patience for those that disfigure themselves to tell the world who they are. More of a pathetic "Look at me" because I'm cooler / tougher than you. The real poser. I have never seen one of these types down at the gun range and until i do, my opinion stands.
