Last night classically trained actor Ralph Fiennes -- a.k.a. Lord Voldemort in the 'Harry Potter' movies -- stopped by 'The Daily Show' (Weeknights., 11PM ET on Comedy Central) and, frankly, things got a little weird.

Host Jon Stewart asked Fiennes for his opinion on who would win in the unlikely event that former GOP presidential candidate Herman Cain went up against Voldemort: "If they were in a sword fight, in your mind, who would be the victor?"

Fiennes pondered this briefly before saucily quipping, "Depends on the length of the wand."

In breaking down the Republican debate that went down this week, Jon Stewart sided with the news organizations in saying that it's basically become a two-man race between Mitt Romney and Rick Perry. He explained the differences in their styles with two sound bites on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central).

"I've put together a plan with a whole series of points of how we can get America's economy going again," Romney said during the debate. Stewart calls him "a guy with a multi-point, fact-based plan that he thinks can get the economy going."

Then there's Rick Perry. Stewart's quote from Perry was, "I hate cancer." His interpretation of Perry as a candidate: "A guy who will punch cancer in the f****** face."

Jon Stewart is still in shock over the US losing its AAA credit rating. Imagine, then, 'The Daily Show' (Weeknights., 11PM on Comedy Central) host's surprise when he found out that other, much much smaller countries have retained theirs.

Yes, the tough graders at Standard & Poor's have still awarded a triple-A rating to little places like Luxembourg, Norway and ... what's this? The Isle of Man?

They've given a better rating to a place with no industry and where big burly men "horse around in the pool all day"?!

Oh, no, that's Man Island. S&P's rated The Isle of Man, that itsy-bitsy British Crown Dependency in the Irish Sea. To Stewart's amazement, the tiny island, famous for its tail-less cats, three-legged signs and dangerous motorcycle races, actually has a better credit rating than the US.

With the advent of Twitter into the social landscape, our news broadcasts have started sounding pretty strange. In the old days, when a news story wanted to talk about reader feedback, they had letters or man-on-the-street interviews, but social media has changed all that.

And, as Jon Stewart showed us on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central), that's not all that's changed.

Now that we're getting instant responses and feedback from Twitter and other like sites, we're hearing Twitter handles instead of real people's names.

With the deadline looming to either raise the debt ceiling, or risk all kinds of potential trouble if we don't, Jon Stewart looked at the Presidential Address from Monday night on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central). After all, the deadline is August 2nd, so he was expecting some harsh rhetoric.

Instead, Barack Obama turned to the American people. "If you want a balanced approach to reducing the deficit, let your member of Congress know," he pleaded. But you'd better do it soon, and you'd better hope they pick up.

"That's your idea?" Stewart asked, after a moment of stunned silence. "Call your Congressman? Did the president just quit?"

First of all, Jon Stewart paid a genuine compliment to Stephen Colbert on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central). That's shocking alone, but the image Neil Patrick Harris created when describing a circus spin move Colbert knows was just as unexpected.

Colbert knows how to do "the spin move" -- which involves two people jumping up into his arms and then him spinning in a circle -- and after hearing both Harris and Stewart describe it we demand to see him perform this move for ourselves.

According to Stewart, "Two more years, he throws out a hip" doing this move, so we'll need to see it as soon as possible. Colbert is sure to watch this episode, because he'll want to clip out the bit where Stewart calls him "a multi-talented individual."

Jon Stewart sat down with author Scott Miller to talk about one of our more forgotten presidents on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central). Miller thinks William McKinley is overshadowed by his successor, Teddy Roosevelt, but McKinley led this country through a very pivotal time in our history.

His legacy as a president, according to Scott and worded by Stewart, is that "his warring ushered us into the Imperial Age."

But the best part was how diplomatically Scott phrased our international holdings and presence after McKinley. "He really introduced America to foreign affairs and provided commitments for us."

Steve Carell's rise to superstardom really kicked off when he was a correspondent on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central) from 1999-2005. From there, of course, he moved on to 'The Office,' where he reigned supreme until he left the show this past season.

As expected, Carell's talk with Jon Stewart was one of the funniest interviews we've seen on the show in a while. We loved Stewart trying to make Carell feel better after the cancellation of his show.

"Well, the show didn't get canceled," Carell told him. "The show continues."

The last time Jon Stewart had Pervez Musharraf on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central), he was the President of Pakistan.

Musharraf was in office from June 2001 until he resigned in August 2008, and he's been in self-imposed exile from Pakistan since his resignation. However, he has plans to return and run for president again in 2012.

But Stewart was more interested in the fact that Musharraf was president while a certain terrorist was holed up in Pakistan.

It was a very candid interview, and Musharraf gave some very direct answers to Stewart, who wasn't holding back in his questions.

It may have come as something of a shock to Jon Stewart on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central), but hardcore fans of the 'Harry Potter' film franchise could tell that Daniel Radcliffe and his acting cohorts remained enthusiastic about the wonder they were creating every step of the way for the past decade.

If nothing else, the huge piles of cash and the fame had to have helped, but we give a lot of the credit to the sheer fun that must have gone into even the hardest days of shooting. It's just such a magical world to be able to play in.

Stewart was more impressed that they were able to navigate their teen years without becoming jaded by the whole experience, "because as a 14-year old, being jaded is in many ways your job."

John Oliver was at the Kennedy Space Center for the last launch of the space shuttle Atlantis. To talk about this end of an era for 'The Daily Show' (Weeknights, 11PM ET on Comedy Central), he spoke with people at the launch, and even sat down with Apollo 13's Captain James Lovell.

While Lovell is a true American pioneer and a NASA legend, he didn't quite give Oliver the gravitas he was looking for in this pivotal moment. So Oliver upgraded to the fictional version: Tom Hanks.

"All peoples need to have certain goals, something to strive for, and in doing so, we reach beyond ourselves to achieve that which we did not think was possible. To give up on that dream is to give up on America," Hanks said dramatically, but Oliver still wasn't convinced it was epic enough. Maybe Forrest Gump?

Just like Republican presidential candidate Michele Bachmann's husband, Dr. Marcus Bachmann, reportedly used therapy to encourage gay people to go straight, Jerry Seinfeld came on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central) to use therapy to help Jon Stewart not crack jokes at Bachmann's more effeminate traits.

And he used the most abrupt and startling therapy methods known to modern medicine ... and barbaric medicine as well. He slapped sense into Stewart when he couldn't control his urges to crack jokes about Bachmann's dance moves or his speaking voice.

Kid Rock's hard-rock reputation took quite the beating on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central). So, in order to make up for it, he threw his tour-mate Sheryl Crow under the bus a little bit.

Jon Stewart started the trouble by declaring Rock "a professional."

"Man, don't blow my street cred," Rock laughed. They talked about how easy it was to coordinate Rock's involvement in Stewart's recent rally, but then Stewart dug that knife a little deeper.

"He would call me and be like, 'Uh, you're gonna need to put this on a DX format with a 550,'" Stewart said. "You're not Kid Rock, you're Nerd Rock."

Jon Stewart was absolutely stunned on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central) after the Supreme Court ruling struck down a California law that would fine retailers for selling violent video games to minors. But the wrinkle to the ruling adds to the ongoing debate between sex and violence in this country.

It was this additional quote that left him perhaps the most confused. "Government might be able to restrict sexual materials, but not violent and other materials."

Stewart then proceeded to warn his audience to vacate the room if they're squeamish as he played a clip from 'Mortal Kombat 2011' of a woman literally being torn in half. This is the kind of game protected under this law.

When you talk to celebrities multiple times as the host of your own late night show, sometimes it's fun to just ask the most inane questions you can think of. Craig Ferguson has built a whole show around it.

But it was Jon Stewart on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central) who asked Tom Hanks the following question.

"In your experience, and I think this is very important, the best smelling actor that you've worked with?"

It was Hanks' own fault for saying that Julia Roberts smelled great in their current project, 'Larry Crowne.' But it wasn't Roberts he declared the best smelling.
