Putin on the black belt
Russian Prime Minister Vladimir Putin is not a politician to be messed with. Weeks after using a tranquiliser gun to stop a Siberian tiger eating a film crew at a nature reserve, Putin marked his 56th birthday with the launch of an instructional DVD on his favourite martial art: judo. On YouTube (Keywords: 'Putin teach'), the former KGB lieutenant colonel impresses with a variety of moves for throwing an opponent to the mat. Putin is best known for using the technique called Harai Goshi, or the sweeping hip throw.
