I'm Captain Kirk! (The Enemy Within)

Aboard the Federation starship USS Enterprise NCC 1701, the good Captain James T. Kirk said "The impostor is not to be injured. Use minimum force. Repeat, the imposter is not to be injured." In Captain Kirk's quarters, the evil Captain Kirk got very angry and said "I'm Captain Kirk!" The evil Kirk then knocked down Kirk's books and said "I'm Captain Kirk." He then knocked the screen to the ground and it broke. The evil Kirk said "I'm Captain Kirk!" Then he screamed in a bestial rage "I'm Captain Kirk!"
