Listen up! Class is in session.

This time around, we talk to the man formerly known as Diesel -- "Big Sexy" Kevin Nash, now performing with Total Nonstop Action wrestling.

Nash, in the main event this Sunday night against NWA champ Jeff Jarrett in the "Bound For Glory" pay-per-view event, spoke with your professor by telephone this week. (To get my picks for that event, click right here.)

As for Nash, he says he's thrilled to be part of the TNA circus, in large part because the Nashville-based promotion has a spankin' new contract with Spike TV, with the weekly "Impact!" show airing on Saturday nights.

"This is the first time the product has had real national exposure," Nash said, ignorning TNA's earlier stint on Fox Sports Net. Not that you can blame his snub. FSN never really got behind the product, burying "Impact!" in the late-night hours.

"To be back on national television is huge," Nash added. "It raises the bar for every guy in the locker room. I'm just looking forward to being part of the company."

Nash, a former WWE and WCW heavyweight champion, says he has a knack for being in the right place at the right time. It was for Nash and former partner Scott Hall who had a huge part in starting the Monday Night Wars of the late-90s. They were the original members of the "New World Order," a heel group which put a supercharge into "WCW Monday Nitro," giving WWE owner Vince McMahon unprecedented national competition at the time.

"If it wasn't for Scott and I jumping (from WWE to WCW), wrestling wouldn't have had its second heyday," Nash said. "I haven't missed too many trains."

With the TNA locomotive trying to steam along, Nash is happy to be aboard. He calls TNA stars A.J. Styles and Monty Brown some of the best workers in the business, and says the show itself could easily expand from one to two hours based on the talent in the locker room.

"We have guys who can eat up 25 minutes like it's nothing. It's got a very fresh look to it," Nash said of TNA. "As these guys become big name players, we're going to build stars. I think our product is giving people what they want."

As for Nash, he has an open-ended TNA contract which basically allows him time off to pursue acting interests. He recently returned from China, where he filmed the video game-based "DOA: Dead Or Alive." He's also had memorable parts in the remake of the prison football movie "The Longest Yard," and Marvel's "The Punisher." Acting is his future, he hopes, but right now wrestling still pays a few bills.

"I'm 46. My wrestling days are numbered," Nash said. "I've had 13 knee operations. I'm beat up."

But not beat up enough to make another main-event return to the ring. Will he beat Jarrett? The smart money says no, simply because it makes more business sense to elevate younger stars for the long run. But then again, Nash has been at the center of wrestling revivals before.

"I'm an entertainer," he said. "Hopefully I've entertained. To be the NWA champion would be a trifecta."
