The Alibi: Larson insists his mook was with him, and therefore couldn't be the person who ran the Dukes off the road.
Are These Wires Important?: Accidental. At the beginning of the episode Luke has recently rebuilt the General Lee's carborator. As they're getting run off the road (see We Need a Distraction below) the carborator starts to act up. Once they have a chance to look at it Bo discovers a couple of screws that Luke apparently forgot to secure.
Bo: I found the problem. [holds up a couple of screws] Couldn't figure out where these went, huh?
Auction: Boss plans to auction Silas's house, worth $50,000, at midnight and arrange for Rosco to be the only one there to bid, so it'll go for a mere $5,000.
Mr. Winkle the ventriloquist uses a remote control early in the episode to control a chair which allegedly has an invisible Rosco on it. This along with Winkle's ability to mimic voices comes in handy later when they're setting up JD to be "haunted" by Silas Hogg. Even Lampshaded:
Waylon: Y'all remember that remote control gizmo Winkle used on the chair with Rosco's voice? Well they're fixin' to use it again.
In the letter Silas refers to JD as his "scalawag" nephew. Later Rosco denies that he and Boss went to the Duke farm to steal a letter where Silas calls Boss a scalawag. Then Daisy asks Cooter if Silas ever mentioned updating his will; Cooter doesn't remember that but he does recall, unprompted, that the last time he was with Silas Silas had seen JD going into the county courthouse and called him his "scalawag nephew." Daisy doesn't pick up on this.
Damsel in Distress: In the final act Larson and his mook hold Daisy at gunpoint in order to take all the money and skedaddle.
Enemy Mine: The Dukes team up with Boss and Rosco in the final scenes to rescue Daisy from the even worse Mr. Larson and his mook, who have her at gunpoint.
Fiery Cover-Up: once Boss has his hands on the letter he burns it.
Flashed-Badge Hijack: Rosco commandeers a young boy's bicycle in order to ride into town when he's stranded out in the wilds of Hazzard without a vehicle.
Gaslighting: During the "haunting" Bo and Luke show up at Silas's house and claim not to hear anything unusual, such as Silas haunting JD.
Waylon: Well just about anywhere Rosco fired he'd hit a Duke. So they freezed. Uh, froze. Uh, they did what he said.
Jitter Cam: Used for some reason when Boss and Rosco are searching the Duke farm for Silas's letter.
Just Testing You: Rosco is confused as to why he and Boss Hogg were going to the Duke farm. When Boss explains that they're going to steal the letter Jesse has naming him as the new executor of Silas's estate, Rosco replies, "Oh, well, I just wanted to see if you knew."
Limited Wardrobe: To dress formally for the reading of the will, Jesse puts a battered suit coat over his regular faded overalls and shirt and trades his usual red cap for a fedora.
Lockdown: Boss makes up a communicable disease that he claims the Duke may have picked up during a short trip in order to quarantine them for 24 hours.
Look Behind You: In the final scene the Dukes go into the Boar's Nest and, since it's crowded they can't find a table, they tell everyone to check out a car wreck right out front. Everybody leaves and the Dukes have their choice of tables.
Lost Will and Testament: Silas's lawyer Mr. Larson "loses" the written will that he had made recently, which named Jesse Duke the executor of the estate, leaving the phonograph record will that Silas made 15 years previously which named JD as executor. Larson does this in exchange for 50% of the estate which he will split with JD Hogg.
No Honor Among Thieves: Boss plans to scam Larson out of at least part of the 50/50 split they have arranged for Silas's effects by selling Silas's house dirt cheap, then giving Larson half of the sale price. Meanwhile Larson is planning on stealing all of Silas's money from Boss.
Not Proven: Judge Carter believes Jesse, but without any evidence such as a copy of the real will or a confession by one of the conspirators there's nothing he can do about it.
The Oner: The scene where Boss and Rosco search the Duke farmhouse for the letter is done in one continuous take on Jitter Cam.
Passed-Over Inheritance: Instead of leaving his money to JD Hogg, Silas Hogg left all his money to charity.
Running Gag: The "say hello from Rosco" bit returns.
Boss Hogg:[on his knees, talking to what he thinks is the ghost of his dead uncle Silas] This is your poor nephew JD Hogg.
Rosco:[also on his knees] Say hello from Rosco.
Boss Hogg: Not at a time like this!
"Scooby-Doo" Hoax: The Dukes set one up, the eponymous "Haunting of JD Hogg," in order to make him confess to there being another will.
Shooting Gallery: While guarding the Dukes during their quarantine Rosco sets up some bottles and practices his Quick Draw.
Spit Take: Rosco does one while drinking out of one of his Shooting Gallery bottles. It must not taste very good.
Tell Me Again: Using those exact words, JD asks Mr. Larson the lawyer to restate his plan.
Try and Follow: The Dukes make a jump in the General Lee in order to lose Larson's mook, who is following them with bad intentions.
We don't hear any details of Luke's plan to haunt JD until we see it in action.
When Daisy is kidnapped Luke draws up a plan to rescue her but we don't hear it because Waylon is too busy narrating that Luke drew up a plan to rescue Daisy.
Video Will: A variant. Silas Hogg recorded his will on a phonograph record 15 years previously. However he rewrote the will a month ago, but it's a regular paper will.
Mr. Larson the lawyer has his mook delay the Dukes from getting back to their farm to bring back a letter naming Jesse the executor of Silas's estate, so that Boss and Rosco can get there first and steal the letter in question. The mook runs the Dukes off the road. Later when the Dukes go to talk to Judge Carter, Larson sends his mook off again.
Later still, Daisy [who Larson hadn't met] tries to distract Larson long enough for the Dukes to set up their haunting plan at Silas's house. However, Larson catches on quickly and catches her deflating his tires.
