As YouTube commenter number one says, there "will never? be a better Rumsfeld interview for the rest of human history":
Pareene provides background on Louis C.K.'s ridiculous question:
C.K. is referencing the theories of former sportscaster and internationally renowned conspiracy researcher David Icke, who has worked for years now to expose the shape-shifting reptilian Anunnaki gods from the constellation Draco. Disguised as humans, they secretly rule the world. For more, seek out Jon Ronson's documentary about Icke, which is is available on YouTube. (Also you can just watch videos made by the people who believe these things.)
