But the Chinese military's latest online recruiting video makes a soldier's life look more fun than the macarena. The brief spot, posted last week on the website of the Ministry of National Defense and going viral, features tanks and fighter jets, as well as soldiers dancing in rows to a quirky hit tune by the Chopsticks Brothers called “Little Apple”. Its lyrics include, “You are my little dear little apple/I can never stop loving you”.

This outrageous display of facial hair configurations made an appearance at the 4th Annual National Beard and Mustache Championships in New Orleans. Luckily Las Vegas-based photographer Greg Anderson was on-hand to give us a front-row seat as the bizarre spectacle of facial hair paraded in front of his camera lens. The championships involved some 150 contestants from the U.S., U.K., and Canada who competed in 17 different categories.
