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.
Free Kimmy - S4-E11
Revealing mistake: When Jane punches Jo at the doorstep, the pool appears just a few yards distance behind Jo, when in previous episodes the pool is located in the center court, at least 100 feet from all doorsteps.
