A TV legend will be visiting “The Big Bang Theory” during May sweeps.
Bob Newhart will guest-star on an episode of the CBS hit scheduled for May 2. He’ll play “Professor Proton,” the former host of a science show Sheldon (Jim Parsons) loved as a kid, TVLine reports. It turns out Leonard (Johnny Galecki) also remembers him.
Sheldon learns that the Professor hires himself out for appearances and gets him to come to the guys’ apartment.
