"The Dover Boys at Pimento University" or "The Rivals of Roquefort Hall" (better known as simply The Dover Boys) is a 1942 Merrie Melodies cartoon produced by Leon Schlesinger Productions and directed by Chuck Jones. It was released by Warner Bros. on September 19, 1942. The cartoon is a parody of the Rover Boys, a popular juvenile fiction book series of the early 20th century. Jones would later remark that The Dover Boys was the first cartoon of his he found to be funny. In 1994, the cartoon was voted #49 of the 50 Greatest Cartoons of all time by members of the animation field.
The cartoon is one of a handful from WB to enter the public domain, due to United Artists - which had bought Associated Artists Productions (later absorbed into WB's own television unit) - not renewing the copyright.
