NEW YORK — 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 “New-hart” 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.”

The Cleveland native also voiced commercials and made guest appearances on numerous TV series, including “Seinfeld,” “Night Court” and “Diff’rent Strokes.”
