Points for creativity? A Mexican man has been arrested after authorities at Mexico City's international airport discovered 18 titi monkeys stuffed into socks and tied around his waist. Roberto Sol Cabrera was returning from Lima, Peru, and had been trying to smuggle in the tiny primates by wearing them slung on a belt under his clothing—“to protect them from X-rays." Two of the monkeys were dead when they were confiscated. Many species of titi monkeys are on the Convention on International Trade in Endangered Species of Wild Fauna and Flora's endangered list, and can be sold for around $1,550 in Mexico.
