IIRC, a few years ago there was an Australian lawyer who wanted to show 
the ineffectiveness of the patent application procedure in Australia, 
and so he filed a patent application for the invention of some sort of 
rotating device (the type that is more commonly known as "a wheel").
The application was approved.
