Squeeze Play - S4-E7
Revealing mistake: When Lola hits back Rick's pitch and gets him in the 'nads, it's transparent in the shot of her swing that the ball was not flying back at the pitcher in a million years. (00:10:55)
Squeeze Play - S4-E7
Revealing mistake: The construction workers in the bar believe Magnum's bluff about being an inspector, and make a run for it trampling him. Tom Selleck's stuntman is the one taking the risk of having a mob of big guys stomp him - and you can actually spot a fake moustache dangling loose during the action. (00:18:30)
Squeeze Play - S4-E7
Revealing mistake: Higgins speaks with the idiotic nephew of the most hated (temporary) new boss, who tells him uncle is in the Den. Higgins opens the door and before it cuts to the new scene, you can peek through the door and see that the lights are switched off; Higgins is walking into an empty room (would be fun if it were the broom closet, but it's actually the correct photoset, just with nobody there).
