Bob Newhart made a delightful special appearance on “The Big Bang Theory” as Sheldon and Leonard’s childhood hero on Thursday night.
Newhart made it look so easy with his timid, halting comic style. In the ’70s and ’80s, Newhart’s eponymous sitcoms routinely averaged more than 20 million viewers. He had a pretty good lead-in initially on CBS: “The Mary Tyler Moore Show.” And this was on Saturday night, folks, with a a lineup that also included “The Jeffersons” and “The Carol Burnett Show.”
Of course, this was back in the day when TV was merely trying to entertain us, before it settled on its current shock-and-awe strategy.
On “The Big Bang Theory” Newhart proved that even at 83, he can get more laughs by subtly raising an eyebrow than Ashton Kutcher can with 50 punchlines.
