The actual line "Welcome to the Monkey House" referred to the following incident, in the story Welcome to the Monkey House: The social reformer who invented pills to numb all men and women from the waste down was spurred to this zealous rejection of all things sexual when, on a visit to the zoo with his family, he looked into the monkey house and saw a monkery playing with his balls. The thought that we and our immediate relatives were so "debased", and that anyone visiting the zoo could see it, led to his creation of pills which eliminated any pleasure to be gained from sex. The goverment later made these pills mandatory as a check on overpopulation. And after the story's protagonist kidnapped, denied her pills, and raped a beautiful Suicide Hostess, he left her a note saying, "Welcome to the Monkey House".
