“Let me tell you something about humans, nephew. They’re a wonderful, friendly people as long as their bellies are full and their holosuites are working. But take away their creature comforts, deprive them of food, sleep, sonic showers, put their lives in jeopardy over an extended period of time and those same friendly, intelligent, wonderful people will become as nasty and as violent as the most blood-thirsty Klingon.”
