Emmy winning comedic actor Bob Newhart will return to guest star in "The Big Bang Theory" in the episode debuting on Nov. 7, 2013 (8:30 p.m. ET/PT), according to a media announcement from CBS Television Network. Along with Newhart, the episode will feature Bill Nye The Science Guy.
Bob Newhart returns as Professor Proton, Sheldon's favorite childhood hero. Professor Proton (Newhart) contacts Leonard (Johnny Galecki) to ask for help with an experiment. Sheldon (Jim Parsons) feels scorned, so he seeks revenge by befriending a rival science TV host, Bill Nye who guess stars as himself.
The announcement that Newhart is returning for another guest appearance comes on the heels of his Sept. 22 Emmy win for last season's portrayal of Professor Proton on "The Big Bang Theory." Amazingly, it was Newhart's first Emmy win, although the comedian has been nominated six times.
In addition to Newhart's Emmy win, series regular Jim Parsons won the Emmy for Outstanding Lead Actor in a Comedy at the 65th Primetime Emmy Awards. Parsons also won the Lead Actor trophy at the 63rd Primetime Emmy Awards. Charlie Sheen presents Emmy to Jim Parsons of The Big Bang Theory
Newhart is best known for two of his long running television comedies, "The Bob Newhart Show" and "Newhart." The series finale of "Newhart," in which he wakes up in bed with Emily (Suzanne Pleshette) has been heralded by many as one of the best series finales of all time.
Newhart was interviewed by The Hollywood Reporter following his Emmy win. Asked whether he had been in contact with producers of "The Big Bang Theory" regarding another appearance. Newhart replied, "We were already in talks. I'm scheduled to do the next episode in October, which means probably sweeps and it’ll probably be on in November. We were already talking about two more appearances."
