The pleasure of sham nudity [pictures of naked people] isn’t limited to humans. In a recent study, male rhesus monkeys were put into an experimental setup where they could choose, by moving their heads, to either receive some sweet fruit juice or to get to look at a picture. There were two sorts of pictures that monkeys would give up the juice for –female hindquarters and the faces of high-status male monkeys. Two major vices –pornography and celebrity worship– are not exclusively human.
