There's no gold in Fort Knox!
Origin: There have been only three visits to Fort Knox's gold depository since its creation in 1935. The length between the visits sparked a conspiracy theory that the gold was not there. Ron Paul recently attempted to pass a bill to have the vaults audited. Some people think that the bars have been drilled out and replaced with tungsten.
Also popular among the aforementioned people who think there's a conspiracy to suppress gold prices.
The reality: In the first visit to the depository since a Congressional delegation went in 1976, Treasury Inspector General Eric Thorson had the lock to the vault opened in front of him and went inside. He emerged fully convinced of the gold's presence, and the absolute security of the vault. He testified in front of Congress to that effect. If you're still not convinced, the Treasury will announce the results of an audit of the gold held at the New York Fed, in which they drilled into the bars to test purity.
