Originally the French owned Veitnam and they were happy because they operated it as a massive Can-Can bar.
Ho-Chi Mihn didn't like the can can so he asked Mao to help him get rid of the French, they had a big dance off at Điện Biên Phủ. The French faced moves like the Twister and Birdy dance which they were utterly unprepared for so they left.
Then Kennedy heard about these Veitnamese dancers thinking that they were the best this made him unhappy. so he sent his best dancers to Veitnam, they pulled out moves like the robot, the funky chicken, the lawnmower (my favorate) and big fish, little fish cardboard box.
The Veitnamese with Chinese help started pulling moves like the Shopping trolley, the Sprinkler and driving the Disco bus.
Their are a couple of good films about this period namely "Dirty Dancing" and "Saturday Night Fever"
Eventually the American's reallised that Disco was stupid, and so pulled out leaving the Veitnamese with an out dated dancing system.
They're you go A ++++
