VIDEO: Jon Stewart Grills & Jokes With President Obama On The Daily Show

Things got a bit tense as Stewart jabbed Mr. Obama over his ability to back up his campaign promises.

"Is the difficulty that you have here the distance between what you ran on and what you delivered?" Stewart said. "You ran with such, if I may, audacity... yet legislatively, it has felt timid at times."

Mr. Obama replied: "Jon, I love your show, but this is something where I have a profound disagreement with you this notion that health care was timid. This is what most people would say is as significant a piece of legislation as we have seen in this country's history.

"What happens is," Mr. Obama said, "it gets discounted because the presumption is we didn't get 100 percent of what we wanted, we only get 90 percent of what we wanted -- so let's focus on the 10 percent we didn't get, as opposed to the 90 percent we did."

Stewart asked Mr. Obama: "Are you disappointed in how it's gone?"

Mr. Obama said he foresaw the growing pains that comes with change, noting his advisers told him when he was elected to "enjoy this now, because two years from now folks are going to be frustrated."

While most of the program was serious political discussion, the president and comedian shared a light-hearted moment - as this was The Daily Show.

Mr. Obama - citing a high-but-declining unemployment rate and downward trends in the housing market as two of the reasons citizens were frustrated with his administrations' performance - proclaimed: "We have done things that some folks don't even know about."

Stewart responded, "What have you done that we don't know about? Are you planning a surprise party for us, filled with jobs and health care?" eliciting laughs and easing the tension in the room.

Mr. Obama replied, "Over and over again, we have moved forward an agenda that is making a difference in people's lives each and every day. Is it enough? No. And so I expect, and I think most Democrats out there expect, that people want to see more progress."
