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.
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.
As My Career Lay Dying - S6-E3
Revealing mistake: At the beginning of the episode, Hank is re-watching Larry's announcement that he won't be renewing his contract after this season. The video tape that he is watching is sticking out of the VCR, which means it's been ejected and can't be playing. His assistant then comes in and says "This again? I'm taking this tape away from you," and removes it, so we know it wasn't on air or from a different source. (00:00:25)
One on One - S5-E7
Revealing mistake: When Coach Norris matches Mark's dunk in their game of HORSE, you can tell that she uses a trampoline or some other kind of apparatus that's off screen to assist her in her jump.
