The Hot Rod - S9-E12
Continuity mistake: When Ike and the Baldwin sisters prepare to enter the "secret" room, in the shot from the foyer Miss Emily lights two new tall candles and they walk through the room's doorway. Then it cuts to inside the room as they all enter through the doorway, but both candles are now significantly shorter. (00:16:25)
The Hot Rod - S9-E12
Continuity mistake: When John-Boy, Jason, and Ben share the Recipe with Jim-Bob for a celebration, John-Boy sits on the bed directly below the picture of the biplane fighters (seen in three shots), but each time it cuts to the shots facing Jim-Bob we see in the mirror's reflection that it's Jason sitting below that picture, and John-Boy is further up on the bed.

The Hot Rod - S9-E12
Continuity mistake: While Miss Mamie is trapped, when Ike and Miss Emily find the special wall panel to control the door, the hidden door opens and the top of the door is plain with no molding, but when Ike leads the Baldwin sisters into the room, in the shot from within the room there is molding across the top of that door.
