  • Kirk gets hooked on uppers and can’t pronounce Lt. Kyle’s name

    Top ten episode, folks. Fantastic piece of writing. The intensity of this episode is one of the best in the whole series right up there with "The Doomsday Machine". The remarkable thing is that there is no planet to beam down to or special guest alien or crew member to bring a refreshing element to the script. It's all done with the regular crew. I get all choked up when Kirk agonizes over who to send into the giant amoeba via the shuttlecraft, McCoy or Spock.
