Revealing mistake: When Sgt. Troy throws the grenade at the Gestapo agents barricaded behind the table, it is thrown wide right, yet the pyrotechnic explosion is dead center of the table barricade.
Surf's Up! Joker's Under! - S3-E10
Visible crew/equipment: After Batman wins the competition, when Hot Dog is finally released from the trash can Joker rushes over to claim it was just a little joke, and the microphone pops up into view at the bottom of the screen. (00:21:10)
Is There in Truth No Beauty? - S3-E5
Other mistake: In the final scene, Kirk is still in the transporter room, but does not have on a visor when the ambassador transports out. Even if he did, humans can still go mad if wearing one and that's why Spock operates the transporter. Spock has his visor on, but then you see Kirk walk out of the transporter room without a visor and he is not going mad.
Continuity mistake: Over the course of many Dark Shadows episodes set in the year 1795, Countess Natalie Dupres' dark, distinct, three-dimensional facial mole changes sides from left jaw to right jaw, briefly vanishes altogether, then returns as a faint, painted beauty mark on her right jaw.
The U.N.C.L.E. Samurai Affair - S1-E27

Continuity mistake: After prying off the lock to the storeroom with the pry bar, Doug drops it on the ground, but the next shot of him entering the storeroom shows it still in his hand.
Revealing mistake: When Briggs disguises himself as Rogosh's defense attorney, the glasses he puts on very obviously have no lenses in them. (00:26:05)
Visible crew/equipment: Oliver (a dog) jumps up on Uncle Bill's bed and starts barking at him. The real reason the dog is barking: in the shots of Oliver, the shadow of a towel or some sort of toy can be seen being waved around in order to agitate the animal. It even briefly pops into the shot a couple of times. (00:10:45)
Revealing mistake: Reid's rear view mirror, missing in all the medium shots (processed in-studio with an obvious rear-screen projection), mysteriously reappears in full shot when his Chrysler pulls into the car shop. (00:14:00)
Continuity mistake: When Davy is telling Mike and Peter that Otto and Sigmund are trying to kill Bettina, the sandwich Mike has switches from his left hand to his right hand in a split second.
The Sleeper Shall Awake/Where Walks the Sleeper/The Final Sleep - S1-E11
Continuity mistake: Part 3: As you see the third "Sleeper" (a giant bomb shaped like the Red Skull's head) note the position of the monocle. First it's on its right side, then its left side, and back again to its right side. (00:14:20 - 00:15:05)
Goodbye, Hello, Goodbye - S1-E2
Continuity mistake: In Season 1, Episode 2 ("Goodbye, Hello, Goodbye"), just before Ann Marie and the doorman enter her new apartment with 2 suitcases and a handbag, a wider view of her apartment shows the same 2 suitcases and handbag sitting inside by the door. (00:03:34)
