Chuck Lorre interviews Bob Newhart about first-ever Emmy win

It looks like seven really is a lucky number.

In a career that has spanned six decades, Bob Newhart had never before received a Primetime Emmy Award, despite landing six nominations over the years.

That all changed on Sept. 15, when the 84-year-old entertainer finally scored an Emmy following his seventh nomination.

Newhart won in the outstanding guest actor in a comedy series category for his recent performance on "The Big Bang Theory." Newhart played "Professor Proton," a childhood inspiration to main characters Sheldon (Jim Parsons) and Leonard (Johnny Galecki).

The award was given to Newhart during the Creative Arts Emmy awards ceremony at the Nokia Theatre in Los Angeles.

Newhart recently sat down with "The Big Bang Theory" executive producer Chuck Lorre for the CBSNews.com "Nominee Spotlight" series to discuss his triumphant win, which left him in tears.

"It was weird because when I saw the Emmy and it was about to be handed to me, it was like, 'Oh my God, I'm going to have one of those things," Newhart told Lorre. "And I turned and the audience was standing, that was just it. It emotionally destroyed me. Because, to a performer, it's from your peers. And that's what's so special about it."

During their chat, Newhart revealed his primary reason for agreeing to guest-star on the hit CBS sitcom.

"In my estimation, it's one of the best written comedy shows on television...and there is no second," Newhart said.

"Coming from you, I'm done. I can leave the casino now. I'm done," Lorre responded.

Newhart shot back, "I hope not."

"The Big Bang Theory" season 7 premiere airs Sept. 26 at 8 p.m. ET on CBS.

The 65th Primetime Emmy Awards airs this Sunday at 8 p.m. ET on CBS.
