It turns out that Professor Proton has a rival!
Bob Newhart will reprise his Emmy-winning role in an upcoming episode of The Big Bang Theory that will also guest-star Bill Nye, CBS announced Wednesday.
When Professor Proton seeks Leonard's (Johnny Galecki) help with an experiment, an angry and jealous Sheldon (Jim Parsons) will get his revenge by befriending rival science TV host Bill Nye of Bill Nye the Science Guy fame.
Nye currently appears on Dancing with the Stars, while Newhart just won an Emmy for Outstanding Guest Actor in a Comedy for his role on the CBS comedy last season.
The Big Bang Theory airs Thursdays at 8/7c. Newhart and Nye's episode is slated to air on Thursday, Nov. 7.
