This was actually a fairly difficult decision between Orko and Snarf. At first, Snarf had the early lead because his name and catch phrase is one of the finest drinking exclamations known to man. Many a night I have consumed to much bourbon, and found myself reduced to only being capable of speaking his name, like that scene in Being John Malkovich, yes, you know which one.
"Snaaarf, Snarf Snarf. Snarf-Snarf-Snarf".
For a moment, I even considered Uni, but quickly decided that while I felt passionately about Uni, my feelings were really nothing more than contempt stemming from annoyance, so I passed.
In the end, after all this carefull deliberation, I went with Orko solely because he had a girlfriend. I don't recall if Snarf had a female counter-part, but I'm relatively certain that if he did he would have in the end chased her away with his alcoholism, and that painfull memory was enough to win Orko my vote.
