In the 90's Warner Bros. cartoon "Animaniacs", the characters Pinky and The Brain are described: "One is a genius, the other's insane." To be quite honest, they both talk and plot to take over the earth. Just because Pinky says "narf" occasionally, and his vocabulary isn't as diverse as Brain's, doesn't make him less than a genius in mouse terms. In mouse-brain terms, I would in fact, label them both off the scale. I would further add that the constant plotting to take over the world would make them both insane.
