People who are relatively intelligent(you do not have to be able to carry on a full blown conversation about quantum physics, but at the same time I do not want someone who ponders the deep and intricate plot behind "The Dukes of Hazard" either). People who have a very dark sense of humor but can distinguish between reality and who knows what else!(For example: We can jokingly discuss setting people on fire, yet I need not have to worry about reading in the newspaper how they actually carried it out that evening!). Lastly, people who have not escaped natural selection through blind luck!
