LAS VEGAS -- He's the most bizarre interview in the sport. Even the most savvy media member can't really crack the conundrum that is Nick Diaz.

So when some fans took their swings at Diaz following the UFC 143 press conference, they found out quickly even the best questions will probably illicit an answer that leaves you chuckling or scratching your head.

The first fan got up and asked Diaz what it would mean to him if there was a day when both he and his brother, Nate, were UFC champions. Diaz slowly grabbed the microphone and then had Dana White repeat the question. Great question, right? The answer was pretty straight forward.

"Yeah, that's what we're working towards. That's the idea," said Diaz (9:15 mark).

Fan No. 2 took his shot and asked about Diaz's "Primetime" quotes, where he said to be a successful fighter, you have to love the sport so much that you have to hate it.

Diaz paused for nine seconds and let out a deep sigh before producing this doozy.

"That pretty much says it, what I said. That's what I meant. That's what that means," Diaz said.

White said Diaz is simply fascinating.

LAS VEGAS -- Gone is the polite Georges St-Pierre. He's been replaced by a guy who has demons in his head.

If anything shows St-Pierre means business about wanting to rip Nick Diaz's head off down the road it was the fact that he sat down with the media for close to an hour on Wednesday. That's when St-Pierre dropped the demon line and talked about having lots of street fights in his past. Diaz is the only bad egg in the UFC's welterweight division.

LAS VEGAS -- UFC president Dana White has routinely given welterweight contender Nick Diaz a hard time for skipping news conferences to promote fights.

In September, Diaz was briefly booted off of UFC 137 after he no-showed news conferences in Toronto and Las Vegas. Circumstances put him back on the card, but it remains a hot topic five months later.

On Thursday at the final pre-fight news conference for UFC 143 at Mandalay Bay, Diaz and White were asked several times about his stance on news conferences.

"He's made it very clear, he's not here to make any friends," White said of Diaz. "He's not looking to have any barbecues over at his house with anyone from the MMA world. He's here to fight. That's it, and I'm cool with that. You just have to show up to press conferences and do the stuff and now, he's doing all of the stuff that needs to be done."

White, though, skipped a press conference last week and didn't do what he needed to do.

They're a necessary evil in the combat sports world. Most mixed martial artists who win them go out of their way to say they don't consider themselves the true champion.

Carlos Condit said as much about his upcoming UFC interim welterweight title bout against Nick Diaz on Saturday night, a bout necessitated by the torn ACL suffered by champion Georges St-Pierre.

"If I win, that's nice, but I'm not the real champ," Condit said. "Everyone knows Georges is the champ until someone beats him."

And yet, interim titles serve a real purpose, keeping a the top of a division focused whenever any of the things that can go wrong in the wild world of MMA occur, from injuries to contract squabbles to brushes with the law.

Diaz-Condit will mark the seventh interim title fight in the Zuffa-era UFC, not counting unification bouts with returning champions. Here's a look at the interim champs over the years and the situations which produced them:

Heavyweight

2005: Andrei Arlovski. Frank Mir's first heavyweight title reign came to an abrupt end in 2004 when he was involved in a motorcycle accident, which nearly finished his career. So Arlovski fought Tim Sylvia at UFC 51 in the first fight of their trilogy, and won with an Achilles lock in just 47 seconds. The extent of Mir's injuries were such that he didn't end up returning until 2006, so Arlovski was later named the official champion and held the title until losing his rematch with Sylvia at UFC 59.

The UFC has gone through many changes and growing pains through the past nine years, but through it all, MMA fans could count on one constant: gladiator man. The anonymous man in a possibly-plastic gladiator costume opened UFC pay-per-views.

Now, he will be replaced by a one-minute long clip that is supposed to encompass all eras of the UFC. The update is to help the UFC get with the times.

"The UFC is heading into a new chapter and taking the brand to the next level," UFC president Dana White stated. "We've had the same show open for the past nine years, and with his monumental FOX deal and the global expansion of the UFC, we wanted to come up with a new show open that paid tribute to the fighters who helped us build the business and grow the sport."

But what of gladiator man? Word is he will enjoy a nice retirement package and is moving to a nice home at Del Boca Vista.

LAS VEGAS -- Roy Nelson isn't afraid to say what's on his mind even if he's risking a beatdown somewhere down the line.

Speaking to the gathered media at the UFC 143 workout day, "Big Country" is a big backer of Junior dos Santos and had nothing but nice things to say about Fabricio Werdum, his opponent on Saturday night. When it comes to the recently retired Brock Lesnar and Alistair Overeem, he's not too impressed.

"Other people have the easier roads [to a title] shot, like Overeem. He beat Brock ... ooh. Now you get a title shot. Whatever," joked Nelson. "Overeem does really good at what he does. He's a good striker. Ground? Maybe not so much. Talk about dos Santos here, all he does is knock people out."

Nelson can crow loudly about JDS because he went 15 minutes with the champ and couldn't be finished.

On the topic of Lesnar, Nelson was pretty blunt during a discussion on his hometown radio station ESPN1100/98.9 FM in Las Vegas.

LAS VEGAS -- Nick Diaz is saying, but he's not saying.

The UFC interim welterweight title challenger showed up for his first round of media duties yesterday in Las Vegas. Our videographer Silton Buendia did a beautiful of piecing together what he could.

On the topic of being the favorite in his UFC 143 fight against Carlos Condit:

"We have a really even sort of record. One of us might ha fought harder opponents. I can't say that I have. I just figure that one of us, with all those fights, one of us has had harder opponents in there," Diaz told the media at UFC 143 workout day. "I know that everybody I've fought has been really, they've been really tough. I've never been fed any squids."

So Condit's resume is less impressive, right? That's exactly what Diaz said, or did he?

On the subject of Georges St-Pierre's ACL injury, Diaz has his doubts yet he doesn't.
