The notion that 9/11 was caused by a group of greedy billionaire oil barons has been dismissed by a group of greedy billionaire oil barons.
"The idea that we would do such a thing it ridiculous. To cause such devastation and mayhem just to create a new world order, is mad". However, it was later revealed the oil baron we just quoted was in fact mad, as he had decided to cover himself in trifle and squeak like a radish.
President Bush was equally scathing of the notions of complicity, "We must put aside these ideas of wild conjecture and conspiracy, and have a burping contest. Me first"
His words have echoed around the world, and so, unfortunately, has his breath.
