Everybody needs a Neck Sock

Take a look at this picture, and try to work out what's going on. Any idea? No? Not a clue?
It's a Neck Sock. You've got your guitars hanging on the wall, but you're worried that the strings might get dusty. So you need a Neck Sock: "The most useful accessory to hit the music world since the guitar strap!" Currently being used by Kings of Leon and Ray Parker Jr, they come in lots of colours, and they're planning a Neck Sock Girl calendar. So, if you're a furry-phallic-guitar-accessory fetishist, rejoice!
