Whatever Happened to... Robot Jones? (simply known as Robot Jones or WHTRJ?) is an American animated television series created by Greg Miller for Cartoon Network. It follows Robot Jones, a teenage robot who attends the fictional suburban Polyneux Middle School in a retrofuturistic version of the 1980s. Episodes follow Robot Jones researching aspects of human life, including music, facial hair, and gym class. Jones is guided by his three friends, Socks, Mitch, and Cubey. Robot Jones is often smitten with his crush, Shannon Westerburg, a tall, young girl with orthodontic headgear and a prosthesis. In school, Robot Jones interacts with his teachers, Mr. McMcMc, Mr. Workout, and Mrs. Raincoat; the principal, Mr. Madman; and janitor Clancy Q. Sleepyjeans. His arch-rivals, Lenny and Denny Yogman, try to sabotage Jones's research by making school more difficult for him.

Miller's first pilot aired on Cartoon Network on June 16, 2000, as part of "Voice Your Choice Weekend", a contest in which previously unaired pilots were broadcast for viewers to decide which should be given a full series. Even though the Robot Jones pilot ranked second below Grim & Evil in the event, Robot Jones was greenlit for its own series, which premiered on July 19, 2002. The first season voice of Robot Jones was created with a Microsoft Word 98 text-to-speech function on a Macintosh computer. Beginning with the second season, Robot Jones's voice was dubbed over by child actor Bobby Block, and reruns of the first season were re-dubbed with Block's voice overs.
