I've looked forward to seeing the Bob Newhart character, Professor Proton. He is over eighty and is still doing kid shows as a TV scientist. He is Sheldon's childhood idol and so the guys hire him. Newhart has the perfect timing to pull this off. I believe him to be the best straight man in TV history. A second plot has Howard and Bernadette dogsitting for Raj.
