Jon Stewart picked apart Senate Republicans for filibustering the Buffett Rule on his show Monday evening, including poking fun at that thought of them considering millions to be more than billions.

Stewart noted how Republicans devalued the $47 billion in revenue the Buffett Rule would bring in but previously considered the $363 million given to Planned Parenthood each year as "a lot."

"Well there's some new math for you," Stewart said. "So let me see if I can get this straight for you: $47 billion in millionaires' money is less than $300 million dollars in mammogram and birth control."
