In “The Proton Displacement,” Professor Proton returns to seek advice from Johnny Galecki‘s Leonard, hurting the feelings of his biggest fan, Sheldon (Jim Parsons), in the process. Being the emotionally stunted individual he is, Sheldon seeks revenge by befriending a rival science TV host, Bill Nye, leading to what appears to be a showdown between the two guest stars.
Newhart first appeared on the show at the end of Season 6, in an episode that won the iconic comedian his first Emmy at this year’s ceremony. Nye is just coming off a short-lived run on Season 17 of “Dancing With the Stars.”
“The Big Bang Theory” airs Thursdays at 8 p.m. ET on CBS.
Are you looking forward to Newhart and Nye’s guest appearances on “The Big Bang Theory”?
