Lieutenant Commander Tuvok
"Tuvok, has anyone ever told you you're a real freakasaurus?"
"I do believe there is more within each of us than science has yet explained."
"When is a Vulcan no longer a Vulcan?"
"You keep working on that sense of humor, Commander Vulcan. You'll get it one of these days."
"The logical course isn't always the right one."
"The human fascination with 'fun' has led to many tragedies in your short but violent history. One wonders how your race has survived having so much 'fun'."
"I have never understood the practice of some cultures of describing ferocious creatures in an attempt to lull children to sleep."
"Vulcans do not have friends."
"Kalto is to chess as chess is to tic-tac-toe"
