The Statue - S2-E6
Continuity mistake: When Kramer gathers the old clothes, shoes, hat from the cardboard box on Jerry's table, they keep changing position in his arms between shots. (00:04:30)
The Statue - S2-E6
Continuity mistake: The first time we see Ray, he kisses his fiancée's hand. Elaine in that shot is holding her papers, with the thicker black book closest to her chest. A couple of shots later when he bows to "Jerry, lord of the manor" the books in Elaine's arms have switched position. (00:05:50)
The Statue - S2-E6
Continuity mistake: Jerry is on the phone with Rava's boyfriend to ask him about The Statue. In the close-up he is holding the cordless in his left hand, but the same hand is on his hip when he is in the background with all the others crowding the landline to listen. (00:12:30)
The Statue - S2-E6
Continuity mistake: During the scene at Monk's, Jerry bumps George on purpose making him spill some coffee. George is holding his cup in the right hand and the menu with the left. In the reverse shot you can see Jason Alexander put the cup down, held in his left hand. (00:14:20)
The Statue - S2-E6
Continuity mistake: George had enough of Ray's pawn shop story and jumps up calling him a thief. Watch the couple at the table; the woman, wearing a purple sweater, has her hand on the man's arm in the reaction shot, when nothing of the sort was happening in the wider angle. (00:15:30)
The Statue - S2-E6
Continuity mistake: In The Statue, George claims to have broken a statue that used to sit on his mantel. However, in season 6, episode 3, "The Pledge Drive," George states that he would be a completely different person if his parents had a mantel.
The Statue - S2-E6
Continuity mistake: Near the end of the episode, Kramer acts like a cop to get back The Statue. The door is almost completely closed. Just before he leaves, the door is suddenly open about one foot, even though it hasn't been touched yet.
The Revenge - S2-E7
Continuity mistake: George walked back into a meeting at his workplace pretending nothing happened. When his boss enters the room, George repeats in two separate the shots, differently, the gesture to hide his face behind a folder. The folder itself changed position before the boss arrived, since it was in his hand at first, then on the briefcase. (00:08:00)
The Revenge - S2-E7
Continuity mistake: During Elaine's amazingly off-putting flirting with George's boss, she starts mentioning how people don't say "Bless you" as they used to. She is gesturing with her right hand pointing a thumb -but before her "Have you noticed that?" is over, she is already in a new shot with hands joined and fingers entwined. (00:16:00)
Continuity mistake: George grabs the slip of paper from Elaine's hand. When he has his 'heart attack', in the shot when Jerry says "What does that mean?" the paper goes from his left hand to his right hand. (00:02:45)
Continuity mistake: Elaine and Jerry guessed that George is telling them about a heart attack. Jerry says "I know what this is" pointing a finger - but in the next shot not only the hand is pointing a finger; the hand is holding the yellow note. (00:03:05)
Continuity mistake: Jerry is smothering George with the pillow when Elaine walks in. First shot and a black nurse is walking behind her. Cut for one second to Jerry, back Elaine and the same guy is still walking, exactly where the view cut the first time. (00:06:25)
Continuity mistake: Elaine walks up to George in bed, and she asks him if anyone's got his apartment yet. For the brief part of dialogue about the zen lifestyle thing, the top sheet is rolled up in a noticeably different way from the rest of the scene. (00:07:00)
Continuity mistake: The doctor is examining George. George yells into the stethoscope so he takes the buds off his ears. Not just that; he removes the instrument and puts it around his neck. George then freaks out and starts naming various odd and even rather harmless conditions; the doc is wearing the stethoscope again. Flirting with Elaine you can see the instrument sorta shuffles around, with part of it exposed and part of it under the scrubs' collar, now the left side, now the right side. When Jerry breaks off their idyll with the Romeo and Juliet reference, the stethoscope is back around his neck, only to be again in use when George asks "With a knife?" (00:08:00)
Continuity mistake: On his deathbed George triumphantly utters "There's nothing wrong with me!"; the doctor cools his enthusiasm down though, saying that he wouldn't go that far. His hands are crossed in front of his body - at the cut though he's suddenly already browsing through George's medical file. (00:08:10)
Continuity mistake: When the doctor tells George that he can have some ice cream, he touches his arm. Difference is, in the first shot the clipboard is in the right hand, in the close-up it's in the left hand. (00:09:20)
Continuity mistake: Tor is introduced; in the reaction shot on Jerry and George to the weird hug with Kramer, Jerry is holding his own leg with his both hands. In the wider shot he just uses his left and with nothing else in it. (00:13:30)
Continuity mistake: During his odd holistic visit, Tor puts both the middle finger on George's temples. New shot, and he is using 2 fingers. (00:14:40)
Continuity mistake: During the visit, whenever George asks questions about hot water (can I use it on my face, can it be lukewarm) his hands have a sudden position change between shots. (00:14:50 - 00:16:00)
Continuity mistake: Jerry gives Tor the piece of paper to decipher; the paper is curled towards him in the reverse shots, and Tor's hand is placed at a different height - just look at the fold. (00:17:30)
Chosen answer: George does mention his brother in the episode "The Parking Space". They actually really never mention anything that contradicts the fact he had a brother though, it just isn't mentioned.
