Revealing mistake: Whilst Bobby is reversing the truck before hitting the flagpole in Bill's yard we see the driveway in front of the truck. The very next shot shows Peggy from behind the truck instructing him how far to go to the flag pole and you can see they have used the same background as the shot before from the other angle. You can tell this as both shots are the same background as both angles despite from different viewpoints are exactly the same items and objects in both shots. Added to this there is a driveway in each shot, and Bill doesn't have 2 driveways in his backyard.
The Great Payne Robbery - S1-E11
Revealing mistake: Watch as the corrupt officer comes in to rob the Paynes. It's dark and Gina supposedly has tackled him, but you can see the officer kneel down and then Gina goes over to him to make it look as if she tackled him down when the lights came back on.
Revealing mistake: During the training montage, right as Mac is about to smash the bottle over Charlie's head, you can see Charlie stop what he's doing about a half-second before being hit, and brace himself for the impact, despite not being able to see it coming. This is confirmed on the DVD commentary.
Revealing mistake: When the couple is breakfasting in Brooklyn their mugs are empty.
The Last Shout: Part 1 - S3-E7
Revealing mistake: Saffy is ironing her boyfriend's shirt and when she has finished he puts it on just before asking her to marry him. When he buttons it up he does so with the buttons and holes misaligned by at least 2 button-holes, and with the collar obviously at an odd angle around his neck.
The School of Hard Knocks - S1-E9
Revealing mistake: In the English dub, when showing the front of the flyer, it has filler text that is not related to what it is about. Also, its Poké Balls are slightly transparent and its picture can be seen through it. (00:05:43)

Revealing mistake: When Luke shows Emma the picture of the hawk, you can see that the camera is fake; it does not have a real screen.
So Then a Bat or A Monkey - S1-E1
Revealing mistake: When Joel puts the dead body in the freezer, the eyes are open. When he pushes the head to the side so he can close the lid the body plainly closes his eyes.
Revealing mistake: When we first see the army of Starks outside Global Dynamics, it's quite obvious that only one of them is actually the actor that plays Stark; the others are merely people who look similar.
Revealing mistake: Halfway through the show, the officers get a flat. As Malloy is getting ready to jack up the car, Reed starts using the lug nut wrench to loosen up the nuts. He repeatedly turns the wrench clockwise, which would tighten the nuts.
Not in the Line of Fire - S3-E15
Revealing mistake: Two thirds of the way into the show, Mike and the mayor are talking in his office. If you look at the Mets hat behind Mike, the NY emblem is upside down.

Revealing mistake: When they are stranded on the boat, the boat is moored in the middle of the harbour by a rope going into the water and water rushing past the boat. (00:17:20)
Revealing mistake: The opening scene was shot twice, complete with a rear-end automobile collision in the foreground for both takes. The initial collision destroyed the taillights of the first car and the headlights of the second car and ruptured the second car's radiator on impact, spilling its contents into the street. The production crew attempted to sweep away the debris with a broom before the scene was reshot. If you examine the roadway before the two cars appear in this scene, you will see a prominent splatter on the pavement that has been swept with a broom almost precisely where the cars impact again moments later.
Mewtwo VS Shadow the Hedgehog - S3-E6
Revealing mistake: During Shadow's Super Shadow transformation, half of the background becomes a green screen.
Revealing mistake: While the ODIN agents are hallucinating, one can be seen looking into the barrel end of an MP40. If you follow him as the scene continues, the gun clips out of the sprite's visible area, and is almost entirely gone. (00:14:30)
Revealing mistake: Patty Duke's stand-in is visible behind Cathy when the family is in the front hall welcoming their aunt.
Revealing mistake: When Ellen and the rest are on the ski lift, it becomes apparent that they are being filmed in front of a green screen because as the lift chair in front of them sways back and forth it disappears into it on the left side. (00:02:05)
