Dale Gribble

Dale Gribble AKA Rusty Shackleford

Dale Alvin Gribble (voiced by Johnny Hardwick) is a character in the animated series King of the Hill. He is an exterminator, bounty hunter, chain-smoker, and paranoid believer of almost all conspiracy theories. Due to his beliefs, he uses the alias “Rusty Shackleford” whenever he doesn’t want his real name known, including when ordering pizza (however he inevitably reveals his identity anyways after a few minutes through one act of stupidity or another, such as use the two names interchangeably with the same person). In the episode, “Peggy’s Gone to Pots,” the original owner of Dale’s stolen alias paid him a visit, and asked him to sign some paperwork so that Rusty could get on with his life. Apparently, Rusty Shackleford is the name of a third grade classmate of Dale’s who Dale thought was dead, but in fact simply moved away. Dale has claimed to have the birth certificate of a child who died in 1953 with the name Rusty Shackleford. It is not know whether this document is real or fake. After this encounter, Dale will probably never use the name again and come up with another one. The neighborhood block charter is the only document he has ever signed with his real name; he refuses to sign any document authorized by a government official. When he speaks, he speaks slowly and hesitates between words, except when excited.
