John A. "Jack" Riley Jr. (December 30, 1935 – August 19, 2016)

NEW YORK (AP) –  Jack Riley, who played a counseling client on "The Bob
Newhart Show" and also voiced a character on Nickelodeon’s animated
"Rugrats," died Friday. The 80-year-old actor died in Los Angeles, according
to his representative Paul Doherty.

Besides portraying grumpy, self-absorbed Mr. Carlin on the 1970s "Newhart"
sitcom and providing the voice for absent-minded dad Stu Pickles on "Rugrats"
and its spinoff, "All Grown Up!," Riley appeared in the Mel Brooks films "History
of the World: Part I," ”High Anxiety" and "Spaceballs."

In a statement, Newhart said Riley created one of TV’s "most endearing"
situation comedy characters with his Carlin portrayal.
