Stephen Colbert weighed in on what he called "the biggest scandal that he had ever forgotten about" which "luckily Fox News had not," the "fast and furious" gun running scandal which led to the House Judiciary Committee voting to find Attorney General Eric Holder in contempt of Congress this Wednesday.

Colbert took the opportunity to have some fun with Fox and the Republicans for their recent conspiracy theory:

COLBERT: Yes, very clearly, Obama started this gun tracking program in 2006, when he hypnotized George Bush. Then he secretly ordered Attorney General Holder to order the Justice Department, to order the ATF to order gun shops to sell guns to Mexican drug cartels, and then lose track of them, thereby panicking Americans to gin up support for the draconian gun control measures that Obama has never introduced.

Colbert also took the opportunity to mock "Joe the Plumber's" new ridiculous political ad he has out: 'Joe the Plumber' Shoots Fruits, Claims Gun Control Caused the Holocaust.
