"CBS This Morning" correspondent Mo Rocca visited North Carolina recently to film a report on homogenizing American accents. And no report on American accents is complete without a chat with N.C. State professor Walt Wolfram about the hoi toiders of Ocracoke. Wolfram, a William C. Friday Distinguished University Professor, has been studying dialects for almost than 50 years and has been at N.C. State for the past 20.

"Studying dialects in North Carolina is like dying and coming to dialect heaven," Wolfram told Rocca. "It's incredible. There's no state that has a richer tradition."

Video of Rocca's report is below and includes "CBS This Morning" host and North Carolina native Charlie Rose talking about this own accent.

Nature: Raccoon Nation (8pm, UNC-TV) - A look at urban raccoons, which are commonplace in big cities like Toronto, New York and Chicago. Night-vision cameras and radio collars provide a glimpse of the raccoon lifestyle, and there's also a look at the damage the critters have done in Japan, where they were imported as pets during the 1970s. Includes comments from a biologist who believes city life is making raccoons even smarter (they will rule us one day!). I know they can be destructive, but man, how adorable are they???

Person to Person (8pm, CBS) - In this revival of CBS's iconic primetime interview show, Charlie Rose and Lara Logan, both of the new "CBS This Morning" (which is very good, by the way), interview newsmakers in their homes and workplaces. Tonight's interviews are with George Clooney, Warren Buffett, and Jon Bon Jovi.

American Idol (8pm, Fox) - The Hollywood Round begins. Finally.

Modern Family (9pm, ABC) - Phil's preoccupation with a business opportunity blinds him to his new partner's inappropriate behavior around Claire.

Duke at North Carolina (9pm, WRAL) - You may not have heard anything about this, but it's happening. If you miss your normal CBS shows, WRAL will air "Criminal Minds" at 2 a.m. and "CSI: NY" at 3 a.m., which is a little different from their normal rebroadcast schedule. 

Revenge (10pm, ABC) - Birdies tell me some pivotal stuff goes down tonight, so pay attention. It may have something to do with the visit from Conrad's father, played by William Devane. Or it may not.

L&O: SVU (10pm, NBC) - Harry Connick Jr. is back. That is all.

Charlie Rose, executive producer and host of the PBS interview show "Charlie Rose," will be giving the commencement address at NC State University next month.

Early in his career Rose won a Peabody award for a piece on soon-to-be president Jimmy Carter, and later won an Emmy for a televised interview with Charles Manson.
