The Big Bang Theory (2007) - 93 mistakes in entire show

Character mistake: When Leonard is explaining his thoughts to Sheldon, during the rant which includes him naming who he intends with the words she or her (eg "She: Penny, Her: Leslie), he states, "Indicating that She: Penny had no interest in me asking Her: Penny out," which makes no sense.

Continuity: When Leonard and Penny are talking in the dryer room, the size of the towel Penny is folding keeps changing.

Continuity: When Sheldon is telling Leonard that he didn't ask Penny out, there is a yellow food-bag on the counter between them that keeps changing it's position with every shot change.

Continuity: Sheldon puts the bag in the bin at the start of the episode so that the handle's are facing the ground. When he gets the bag out, the handles are at the top of the bin.

Revealing: Most of the time, though not all the time, Leonard has no glass in his glasses.

Continuity: At the end when Sheldon has got a burger, the amount of burger left changes depending on the camera angle.

Continuity: When the guys are using the whiteboard to figure out their cinema plans, Sheldon draws two black X's on the board with a marker. In the following shots the appearance of the X's changes.

Continuity: In the laundry room when Penny is talking to Sheldon, Sheldon takes some time arranging a blue shirt on his plastic laundry folder. Then it suddenly turns into a pair of socks, which he folds and then picks up the blue shirt again. There was not enough time for him to switch out the shirt for the socks.

Continuity: At the buffet table when the gang gets food, Howard walks in with his 'date.' Between shots, as he walks in, in one shot Sheldon puts his right hand up on his plate. In the next shot his hand is down.

Continuity: When Sheldon, Howard and Raj play Jenga, there is one block sitting at the top of the tower. When Leonard walks in, there are now two blocks at the top, before we actually see Howard place the second one on the top.

Factual error: Sheldon puts the sword up for sale on eBay. He then says, after only four seconds, that someone had "bought it now". Ebay items take up to an hour to appear in the listings/search results. So in 4 seconds, it was listed, Howard found the item, went through the standard purchasing form and bought the item. There is no way to find, and buy, an item in 4 seconds.

Continuity: In the scene where Leonard is packing up his collectables to sell, at 15:32 he is dusting what appears to be a Hasbro Marvel Legends Yellow jacket figure, which also has a yellow post-it on the back. At 15:42 he is still dusting a figure but he now holds a different (darker but not yellow) figure from the same series, with no post-it on the back, and the Yellow jacket figure is now on the table (house left of the box of collectables). At 15:56 The Yellow jacket figure has disappeared from the table, and it is not the figure in Leonard's hands either.

Continuity: When Penny puts the box down at the start it is closed. Camera cuts and it's open instantly.

Continuity: At the end, Sheldon fires 5 shots at Leonard, who somehow ends up with 7 distinct paintball marks on his chest.

Continuity: When Sheldon is in Penny's apartment trying to get her to tell him why her relationship with Leonard failed, the yellow tee-shirt on the red pillow next to him keeps changing position.

Other: Leonard sends a very long text to Stephanie. However it only takes him five seconds to write this long text.

Revealing: When Sheldon gets the sword for Penny in the game, Penny walks out and you can see the laptop isn't switched on.

Continuity: When Leonard and Sheldon are walking downstairs, Sheldon stops and pins back up the caution tape that is in front of the elevator. Between shots, the other strip of caution tape untwists itself.

Other: Raj plays the message on his phone. Howard then takes the phone and instantly, physically dials her number, despite the fact he did not look for it and does not know her or her number.

Continuity: When Raj is going through the ideas on what would work to fix the toilet, Sheldon's hand is not near his face, but when Howard talks about moving to Israel, Sheldon's hand is up by his face.
