When I got to work with alongside him onTBBT, it was absolutely a dream come true.
He was effortlessly professional, poised, hilarious, and incredibly approachable.
How he will be missed!"
Kaley Cuoco(Penny Hofstadter) was just as complimentary.
“He was classy, kind, generous and absolutely hilarious.
Every take every time.
Our dearest Bob Newhart.
Miss you forever.”
