Experiment in Terra - S1-E22

Revealing mistake: When Starbuck veers off the shot of his thumb and the flight stick is reversed. The "IM" button is on the left and the red "FIRE" button is on the right, opposite from where they normally are. Sharp eyes can even see the word "TURBO" is reversed before Starbuck's thumb covers it. (00:03:18)

Revealing mistake: When Bond and Tibbitt are in the underground lab the big henchman takes out Tibbitt. When the henchman turns to take out Bond you can see Tibbitt in the background unconscious. It is not Patrick Macnee but a stunt double. (00:38:30)

Family Values - S8-E9

Revealing mistake: Paul Devildis calls the bank to discuss his restructuring plan. During the shots of the two bankers, on the desk is a notebook-sized, plain brown box. It is very distinctive as it is blank except for a single square white label on the front. Later in the episode Paul delivers his restructuring plan with the bomb inside to the bank. It is in this same box.

My Cold Shower - S6-E19

Revealing mistake: Right after Dr. Cox gives the results of the patients STD tests, the shot switches to show Turk, JD, the Todd and Dr. Kelso. Before the sprinkler activates you can tell that their hair is already wet from previous takes.

Revealing mistake: When Max and 99 climb onto the SUV to try and get on board the plane, 23 trips Max who then knocks 99 off her feet. As she falls, you can see the black cable used to keep the stunt woman from falling off the SUV.

My Big Bird - S5-E8

Revealing mistake: When JD is kicked through the window by the ostriches, watch the window. It fractures about a half a second before JD hits it.

School Days - S1-E3

Revealing mistake: When Max is being attacked with throwing knives, one is thrown into the closet door. Watch closely; the wire used to guide the knife is visible.

My Friend With Money - S6-E5

Revealing mistake: Watch the line appear on the wall as Kelso cuts through the wall into the "Luxury Suite." The line is being cut with a round, drywall cutting bit such as would be used with a drill or Dremel tool. You can see it spinning as the cut is made. However, when Kelso has pushed down the wall and points the tool at Cox and the Janitor, he is now holding a standard reciprocating saw with a flat blade which would cut very differently than what was shown.
