I'd say that's the most ridiculous thing I've ever heard, but I have heard a few things more ridiculous.
Such as...
The claim that Goldman Sachs runs the U.S. Treasury.
The claim that Baxter International has developed a bird-flu vaccine that kills people.
The claim that Representative Alcee Hastings and the House of Representatives are planning to build at least six labor camps for political prisoners.
The claim that Venezuelan President Hugo Chávez owns the software that runs American voting machines.
The claim that FactCheck is untrustworthy because of its links to the Annenberg Foundation.
All these are lesser-known conspiracy theories promoted by "birther queen" Orly Taitz, btw.
