The Professor: coolly analytical, he knows every answer. He’s logical, introverted, and inflexible, but genuine about his feelings. At work, he likes cold, hard facts, thank you very much, but he's also honest and faithful, and won’t let you down. Think Leonard Nimoy in Star Trek, Robin Williams in Flubber, Kelsey Gramner in Frasier, Russell Crowe in A Beautiful Mind.
