"During the late 1940s, Mr. Delmar captivated 20 million radio listeners every Sunday night with his burlesque of a bombastic, super-chauvinistic legislator who drank only from Dixie cups and refused to drive through the Lincoln Tunnel," wrote "The New York Times". "His stock expression, 'That's a joke, son,' was for many years one of the nation's pet phrases, mimicked by children and businessmen alike. ... The windbag character, he said, was inspired by a Texas cattle rancher who had picked him up while he was hitchhiking and barely stopped talking." Delmar was later heard by a later generation of television watchers via the animated character called The Hunter which he voiced using his Senator Claghorn inflections, including, "That's a joke, son." "The Hunter" was a dog detective whose nemesis was The Fox, a criminal fox who attempted bizarre capers, usually huge in scope (such as attempting to steal the Brooklyn Bridge, the Statue of Liberty or, in one episode, the State of Florida). The Hunter ran as an ancillary segment of the cartoon series King Leonardo and his Short Subjects, produced by Total Television Productions.
