I grew up desperately wanting to be Dr. McCoy... and instead, I became Nurse Chapel. Well. Kinda, anyway.

My favorite episodes:

Balance of Terror. Even though I've since seen "Enemy Below," the WWII film this episode is loosely based on, I think this is one of the best tellings of this particular story, ever. Plus? The Romulans!

Amok Time -- Explored Spock's world, pitted friend against friend, and had priestesses in diaphanous dresses. What more can you ask for?

Metamorphosis -- We meet the inventor of the Warp Drive, and an alien who loves him so much, it's willing to accept (eventual) death for him.

Space Seed -- Khan Noonian Singh makes his first appearance... and almost throws Kirk off his own ship!
