Actor. Born John A. Riley Jr., he was best known for playing the neurotic patient Elliot Carlin on the 1970s sitcom "The Bob Newhart Show." After attending Saint Ignatius High School and John Carroll University, he served in the United States Army. Upon being discharged, he became a popular radio personality in Cleveland, Ohio doing a show with his radio partner and "straight man" Jeff Baxter. The Baxter & Riley Show on WERE (1300 AM) featured not only music but comedy sketches and a slew of offbeat characters which Riley and Baxter voiced. The show expanded for a time to local television on WEWS. He gave up the radio show in the mid 1960s and moved to Los Angeles, where his friend Tim Conway helped him receive work writing comedy sketches, which later led to acting opportunities. His first appearance in films came in the 1962 film "Days of Wine and Roses." He later appeared in the television series "Occasional Wife" from 1966 to 1967.

After "The Bob Newhart Show" ended, his television credits included "Barney Miller", "Eight is Enough", "Fantasy Island", "The Love Boat", "Night Court", "ALF", and "St. Elsewhere." Later in his career, he was the "voice" of Stu Pickles in the "Rugrats" franchise, which consisted of the TV series, the spin-off "All Grown Up!", the film trilogy, and three separate video games.
