Pavel Chekov
- Chekov: [darkly] Give some more blood, Chekov. The needle won't hurt, Chekov. Take off your shirt, Chekov. Roll over, Chekov. Breathe deeply, Chekov. Blood sample, Chekov. Marrow sample, Chekov. Skin sample, Chekov. If-if I live long enough, I'm going to run out of samples.
- Sulu: You'll live.
- Chekov: Oh, yes, I'll live, but I won't enjoy it.
- Nurse Christine Chapel: [in a scene often deleted for syndication] Come on, Ensign. It won't hurt. Much.
- Chekov: Promises.
