Yes, having watched every episode of David Carradine's classic 1970's hit "Kunfg Fu" I know quite alot about it! Oh yes!
It has many advantages. Firstly it is shrouded in mystery, so people can make up all kinds of bollocksy stories about how this or that master could do amazing things, like crack a nut with his jacksie, things like that.
Also, you get to wave your hands about in a cool dudey fasion, and someone who is a total tit may think it means that you know how to fight......
There are drawbacks, however. You can only leave the training hall by picking up a boiling cauldron with your forearms, leaving the most amazingly mysterious dragon shaped burn marks. But's its a real pisser when you get them in the wrong place. Practice on a kettle first, but order your taxi to th hospital before you put the kettle on. Basic time management.
Also you have to shave your head and look like a knob.
On the whole I would recommend sticking pins in your eyes before signing up for a course.
