Q: How many members of the U.S.S. Enterprise does it take to change a light bulb?
A: 7. Scotty will report to Captain Kirk that the light bulb in the Engineering Section is burnt out, to which Kirk will send Bones to pronounce the bulb dead. Scotty, after checking around, notices that they have no more new light bulbs, and complains that he cant see in the dark to tend to his engines. Kirk must make an emergency stop at the next uncharted planet, Alpha Regula IV, to procure a light bulb from the natives. Kirk, Spock, Bones, Sulu, and 3 red shirt security officers beam down. The 3 security officers are promptly killed by the natives, and the rest of the landing party is captured. Meanwhile, back in orbit, Scotty notices a Klingon ship approaching and must warp out of orbit to escape detection. Bones cures the native king who is suffering from the flu, and as a reward the landing party is set free and given all of the light bulbs they can carry. Scotty cripples the Klingon ship and warps back to the planet just in time to beam up Kirk et. al. The new bulb is inserted, and the Enterprise continues with its five year mission.
