The Cooper-Hofstadter Polarization - S1-E9
Continuity mistake: The video of the fight we see on Youtube is different to what we saw earlier in the episode.
The Recombination Hypothesis - S5-E13
Factual error: Leonard lies to Sheldon about his being over at Penny's at 3am by saying he went across the street to use the gas station bathroom. Sheldon refers to it as "The Colorado Boulevard Chevron." The address of their apartment building is 2311 N. Los Robles. Colorado Boulevard is five miles away. (Yes, it's a fantasy sequence, but even in Leonard's head, Sheldon's not likely to make a mistake like that). (00:15:45)
The Vengeance Formulation - S3-E9
Continuity mistake: When Howard is proposing to Bernadette she is holding a tray with two glasses on it. The glasses are next to each other, side by side for two shots of her. Then in the third shot the glasses move so one is behind the other. Then in the fourth shot they are side by side again.
The White Asparagus Triangulation - S2-E9
Continuity mistake: When Sheldon, Raj and Howard are talking in the cafeteria, Sheldon's drink keeps moving position.
Continuity mistake: In nearly every episode, Sheldon demonstrates his OCD when he knocks three times on a door, says a person's name, and repeats that sequence twice, for a total of three iterations, but in this episode he radically departs from that behavior not once but twice. First, wanting to talk to Leonard, he knocks four times, says "Leonard" and repeats the sequence three times for a total of four iterations. Later, wanting to talk to Penny, he knocks four times and says her name, repeating that sequence at least four more times. Given that this was the first season, I assume the writers had not yet settled upon the 3x3 routine as a comic behavior.
The Grasshopper Experiment - S1-E8
Continuity mistake: When Raj is drinking with Lalita in the bar Penny works at, in one shot he raises his Grasshopper drink to his lips with his left hand. In the next shot it's in his right (this is just before he says "Oh my God, you've lost so much weight").
Character mistake: When Leonard and Sheldon sit down for lunch at work, Sheldon grabs the salt and pepper and begins to shake the "shakers" over his food. However, these are grinders and not shakers. He would have had to twist the tops in order to get any salt or pepper. (00:16:10)
The Rhinitis Revelation - S5-E6
Other mistake: When Mary is rubbing VapoRub on Sheldon's chest, she makes a comment that last time she saw that there was no hair, to which Sheldon replies "Yeah it filled in last year." In Season 1, Episode 11, Penny rubs VapoRub on Sheldon's chest and a very clear remark about chest hair was made. Season 1 for the show was 4 years ago.
The Cooper/Kripke Inversion - S6-E14
Character mistake: As Leonard is leaving the Mechanical Engineering lab, the sign on the door is spelled incorrectly as 'resticted area' instead of 'restricted area'. (00:04:07)
The Pancake Batter Anomaly - S1-E11
Continuity mistake: The way Penny holds her notepad when talking to Sheldon at the Cheesecake factory keeps changing instantly. (00:10:10)
The Habitation Configuration - S6-E7
Continuity mistake: When Wil first enters Fun with Flags, he has his flag partly on the table in front of him. In the next shot, the flag is not on the table at all.
The Comic Book Store Regeneration - S8-E15
Continuity mistake: While in Penny's apartment, Sheldon is folding laundry and Penny is talking to him from the kitchen counter. Between shots, the water bottle in front of Penny moves by itself to different spots on the counter.
The Russian Rocket Reaction - S5-E5
Character mistake: Sheldon says he drove for hours in a bus to meet Wil Wheaton. He meant he rode on a bus. Sheldon never would've made that semantic error.
The Retraction Reaction - S11-E2
Continuity mistake: Sheldon's formulae are written on three whiteboards. The marker color on the leftmost board is first red, later black. (00:07:05 - 00:09:21)
The Proton Regeneration - S11-E6
Character mistake: While bedridden after his vasectomy, Howard asks Bernadette to grill up a couple steaks instead of picking up Chinese for dinner. She gives him a disapproving look and he says "Kung Pao Chicken, please." A major ingredient of Kung Pao Chicken is peanuts. A major allergy for Howard is peanuts. (00:09:04)
Suggested correction: Since they are both quite well aware of it, they likely have either found a Chinese restaurant that doesn't use them, or they get it without peanuts.
Yup. My friend is allergic to peanuts and our local Chinese restaurant makes hers with almond instead of peanut.
The Troll Manifestation - S8-E14
Continuity mistake: When the gang and Stephen Hawking are video chatting, the Android mascot is lying down when the camera is facing the gang, but when the camera is facing Stephen Hawking, the Android mascot is standing up.
The Bath Item Gift Hypothesis - S2-E11
Continuity mistake: Near the start, when the camera is on Raj, David Underhill is seen in the top left-hand corner of the screen shaking someone's hand, already in the cafeteria. Then, when the camera is on Wolowitz, David is just walking into the door of the cafeteria. David sits down to the right of the man sitting at the table, then shortly afterwards David is now sitting where the other guy was, originally.
The Griffin Equivalency - S2-E4
Continuity mistake: When discussing what qualities their new friend should have, the container Howard has changes position instantly. (00:17:20)
The Griffin Equivalency - S2-E4
Continuity mistake: When talking about wanting a griffin, the bottles and strip of paper on the table keep moving between shots. (00:16:00)
The Comic Book Store Regeneration - S8-E15
Continuity mistake: While Bernadette is talking with Howard about Stuart living in Mrs. Walowitz's home, she is taking items out of a grocery bag. One of the bags of food changes spots on the table in the next shot.
Suggested correction: Sheldon is probably joking when he tells Mary his chest hair filled in the previous year.
Sheldon doesn't make jokes.
Ssiscool ★
He doesn't understand sarcasm, hence, doesn't know when to be sarcastic.

If Sheldon didn't make jokes, the term "Bazinga" would have never came into play. Ever.
ckbyers
And nearly all instances of Bazinga are not used in a funny circumstance. Indicating poor judgement and lack of knowledge regarding jokes.
Ssiscool ★
They were funny to him. And to the audience.
lionhead
Google "how many times has Sheldon said "Bazinga" " - and it'll explain that he does, indeed - joke.
