Another Doctor Who one. In one story, Davros has installed himself as a famous doctor, curing all sorts of diseases at a suspended animation repository. In truth, he has turned many of those present into Daleks, and the others he used as a form of protein concentrate to resolve a famine in that part of the galaxy. The Doctor, naturally horrified, asks Davros is he told those who enjoyed his protein concentrate whether they were eating their own dead relatives. Davros' reply is priceless:
Davros: Certainly not! That would have created what I believe is termed 'consumer resistance'.
