Leonard 'Bones' McCoy: I told you people I don't need a doctor, dammit - I AM a doctor!
Flight Officer: You need to get back to your seat.
Leonard 'Bones' McCoy: I had one. In the bathroom with no windows.
Flight Officer: You need to get back in your seat, NOW.
Leonard 'Bones' McCoy: I suffer from aviophobia - it means fear of dying in something that flies!
Flight Officer: Sir, for your own safety, sit down or else I'll make you sit down!
