This is probably opening a can of worms, but what is your favorite kung fu myth?

* existence of a "death touch"
* one-punch kill
* real kung fu masters can manipulate their chi to cure cancer
* your Sifu is the Deadliest Man Alive
* push hands can lead to devastating sparring ability
* a year of kung fu will allow you to disarm knife-wielding psychos and multiple attackers
* your gi-wearing sensei learned his art directly from the Shaolin Temple
* the Shaolin Temple is the source of all martial arts in China and the World
* MMA people are the Best Fighters In The World
* Bruce Lee would have beaten Muhammad Ali in a boxing match
* Size, Strength, Age, and Gender mean nothing if you have the right skills
* your art is superior to every other art ever created

Etc. Each myth has its origins in truth, but we tend to exaggerate a truism to the point of non-credulity. To avoid the flames, I didn't mention any specific styles or names, but if you are wincing a little, perhaps there is a sacred cow in your yard that you need to poke.
