6 years ago
Bob Newhart, will once again grace The Big Bang Theory stage by reprising his role as Sheldon and Leonard’s childhood idol Professor Proton later this season. This marks Newhart's third appearance on the popular CBS sitcom, having made his grand debut to the series last season, along with an additional encore performance this past November. There’s no word yet about what exactly brings the professor back into the Big Bang Theory fold. But either way, it's bound to be fully charged with laughter.
