A case of mistaken identity in the academic world, via Matt Yglesias:

An Oxford engineering student was surprised but undaunted when he was approached to deliver a series of lectures in Beijing on global economics.

Matthew Richardson knew "next to nothing" about the subject but, believing he would be addressing a sixth-form audience, he felt he could "carry it off".

Mr Richardson, 23, borrowed an A-level textbook entitled An Introduction to Global Financial Markets from a library and swotted up on its contents on the flight from London to China.

Highly entertaining.
