President George W Bush and John McCain are one and the same - a shapeshifting lizard alien from the Zeta Reticuli star system.
The revelations come from an insider from Bush's own staff. Speaking on condition of anonymity, Mr X said he could no longer stand the horrific sights to which he was subject as the alien being shifted from one hideous form to another.
"There's a lot of credibility to these accusations, as the two 'men' are rarely seen in the same place," said one Washington insider. "And when they are, I'm told that the 'Bush' is actually one of the many doubles the President uses for less-important speaking engagements."
Others inside the Beltway have long suspected that the President might be from another planet. According to one Congressman, the Bush-McCain creature's extraterrestrial origins were betrayed in a number of ways.
"The first clue that Bush was an alien was his trouble with even simple English phrases," he said. "According to briefings I've received from the CIA and NASA, language is an alien's weak point. And McCain has similar problems. Sometimes you think he's just not going to get to the end of the sentence."
There is also Bush's bizarre empathy with 'illegal aliens' - with proposed amnesties, citizenship programs and guest worker schemes. "You and I know that 'illegal alien' means Mexican," said the Congressman, "but Bush gets easily confused."
Political experts say that Bush is just morphing his form to get around the two-term limit imposed by the 22nd Amendment. "He hasn't finished with the country yet," said Mr X. "This way, he gets to continue the same policies while convincing people he stands for something new."
The Congressman added: "It's possible that all the neocons - not just Bush-McCain - are shape-shifting lizards and that there aren't nearly so many of them as people think."
