The Ghost of General Lee - S2-E6
Continuity mistake: When the bad guys from Sweetwater county try to steal Boss' safe, you see them pushing it up a ramp into the pickup truck. But in the next shot, when Daisy calls the operator, the safe is in the corner. And when Bo and Luke go to untie Daisy, the safe is gone.
Continuity mistake: During the scene in Mrs. Garrett's bedroom the flowers in the vase keep changing position.
Continuity mistake: In the opening credits, there is a fire hydrant and a red painted curb in front of the building. In the closing credits, there is no fire hydrant and the curb is not red - yet the building shown behind is still the same location as in the opening credits.
Continuity mistake: When we see the pizza stand at the beginning, you can see there is nothing on the counter when the Mystery Machine drives past it. But when Scooby goes up to the stand, a plate of rolls and a napkin holder with two pots have appeared.
