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.
Planet of the Slave Girls - S1-E2
Continuity mistake: When Buck goes to run out of the door of the factory, it's a solid door, with a bar-type handle. When the scene shifts to the outside, the door he runs out of leads directly inside, but the door has vent slats on the lower half, and the handle is completely different.
Continuity mistake: When Shaggy, Scooby and Scrappy have finished perming the lion's hair at the Coliseum, Scooby grabs Scrappy and sends the lion for a spin in his chair. In the next shot, the emperor says "Get off with the lion!" and he pulls a leaver releasing the trap door. But when we see saw the lion falling through the trap door, the barber's chair is nowhere to be seen.
