Alternating broken/whole rear windshield on the General Lee throughout the episode.
As the Duke Boys are running through the woods while being shot at, Bo's shirt changes from yellow to white to yellow again.
The hubcaps on the hit men's Mercury Cougar disappear and reappear throughout the show sometimes within the same chase scene.
When dressed as J.D., Roscoe has a wad of cash in his hand when he is arguing with Cooter over the repair bill, but in the shot of Cooter saying that Roscie was behind the door when they passed the brains out, Roscoe's hands are empty as he reaches in his suit for a cigar.
Remaining patches of glass in the General Lee's broken rear windshield change between shots while the mercs are pursuing the Dukes and Hogg.
The mercs are holding the gas pedal down to try to get unstuck, yet the accompanying sounds are of an engine being repeatedly revved.
Roscoe is never shown to have given Cooter the "25 cents on the dollar" payment for the repairs to Boss's car, yet Cooter later demands that J.D. pay him the rest of the bill in addition to what Roscoe had already paid him.
