Grady Byrd was Boss Hogg's cousin and night watchman at the gravel pits for 20 years before he finally gave him the chance to fill in for Rosco Purvis Coltrane. Grady first appeared in "Officer Daisy Duke". While Grady did his best to live up to Boss Hogg's low expectations, it quickly became clear that Grady wasn't going to be a success at his new job. Grady left the job two episodes later and was followed by Buster Moon.
