Bush was on his third day of a four day coke binge, and in between sips of natty ice and watching cinemax, decided to forge some documents in magic marker, which single handedly resulted in America going to war in Iraq. Also, 911 never happened. Bush knocked out everyone in the country with sleeping gas, kidnapped everyone who died on 911 and sent them to guantanamo, replaced everyone else with dopplegangers and used robots disguised as Muslim hijackers to carry out the attacks.
Stay tuned folks. Evidence will be forthcoming.
