Eww factor 10. I *do* eat low-fat margarine as well as butter
  and have no qualms about it. Actually I don't care for either,
  but as a human, I'm a true omnivore and will eat nearly
  anything. Still, butter/margarine debate aside, its still
  interesting to get a peek inside of an ant's brain for a second.
