You can do a lot of things with your hands. Without them, not so much. One thing you can do, as this dude from China has proven, is put your pants on. It involves a lot of dexterity and flexible legs, not to mention a few dance moves that you often see Shakira doing. Can't imagine how it's done? Hit 'play' to see for yourself.
Now you might be inspired to try doing this at home--nothing wrong with that, just make sure that there's no one else while you're doing it. For obvious reasons. Enjoy!
