The Big Bang Theory will soon welcome a television legend.
Six-time Emmy Award winner Bob Newhart has signed on to portray Professor Proteon, the former host of Sheldon’s favorite science series from many years ago.
Show sources tell TV Line that Sheldon will track down Newhart’s character online and learn that he’s available for parties and events. Naturally, he therefore invites to “professor” over to his home.
The Big Bang Theory Season 6 is off for the next two weeks, while this episode will air on May 2.
