This episode marks the first use of a plot that would become much reworked in the show, that of one of the main characters suffering severe personality change. It would be used for Bo later this season in "My Son, Bo Hogg", and for Luke in the fourth season's "Goodbye, General Lee" and season seven's "Dr. Jekyll and Mr. Duke", and Daisy in season six's 'Heiress Daisy Duke'. It is also used of sorts for Rosco in the sixth season's "Too Many Roscos", where Rosco's place is taken by an impostor. More specifically, the 'personality change' idea would be used for Boss Hogg a number more times, including season four's "Nothin' But the Truth", and in season seven's "No More Mr. Nice Guy". We also see Sorrell Booke play Abraham Lincoln Hogg, Boss's kind hearted identical brother, in "Baa, Baa White Sheep" a few episodes later in the third season.
Cletus is looking under the General's hood.
Cletus: Where's the dipstick?
Bo: You're under the hood, Cletus.
In the episode Grannie Annie, Rosco cries his eyes out he's so choked up that the Boss is gonna get killed by some bad guys, but in this episode when Rosco figures out the Boss has got 2 weeks to live we see Rosco with his feet up on Boss's desk smoking one of his cigars.
This might be explained that in "Grannie Annie", Boss's life was in immediate danger, whereas here, Boss seemingly has two weeks left - maybe it would have hit Rosco nearer the time?
Dennis Haskins is best known for his role as Mr. Belding on Saved by the Bell.
According to the DVD commentary of the first episode, "One Armed Bandits", he is an uncredited extra in the Boar's Nest in that episode.
