On his show Monday night, The Daily Show host Jon Stewart responded to criticism from Nobel prize-winning economist Paul Krugman.

In his column, Krugman attacked Stewart for lampooning his idea of minting a $1 trillion platinum coin to avert the looming federal debt ceiling battle. Krugman said Stewart typically employs "knowing jokes," but had lazily reverted to "yuk-yuk-yuk they’re talking about a trillion-dollar con hahaha." He later said in an interview that Stewart was tarnishing his brand of humor.

"If someone is ruining their brand with a trillion dollar coin idea, I don't think it's the non-economist," Stewart remarked.

"Look, as with most bits we do, whether of the fully fleshed out or more drive-by variety, there are always various counterarguments and nuances of language and thought that can be cited as evidence of this show's inherent unfairness or ignorance," he added. "So, I stand by our research on the topic, the due diligence, and my ignorant conclusion that a trillion dollar coin minted to allow the President to circumvent the debt ceiling, however arbitrary that may be, is a stupid fucking idea.

"And I'm a fan."
