I was just looking for the mathematical 'proof' that 0=1 with a view to demonstrating that 1+1+0=3 (as you do) when I found this, which rather tickled me:

"Proof by intimidation is a term used mainly in mathematics to refer to a style of presenting a purported mathematical proof by giving an argument loaded with jargon and appeal to obscure results, so that the audience is simply obliged to accept it, lest they have to admit their ignorance and lack of understanding. The term is also used when the author is an authority in his field presenting his proof to people who respect a priori his insistence that the proof is valid or when the author claims that his statement is true because it is trivial or because he simply says so."
