VIDEO : Bob Newhart Returning For 'The Big Bang Theory' Final Season

With only one season of The Big Bang Theory remaining, the CBS sitcom will likely pull out all the stops. Of course, one the top guests on every Big Bang fan's wishlist is TV legend, Arthur Jeffries.

Thankfully, the powers that be are going to give fans at least one more episode with Professor Proton.
Bob Newhart will reportedly reprise his role in an episode that is set to air this fall. This will mark his sixth guest appearance as Arthur Jeffries.
