The Thespian Catalyst - S4-E14

Revealing mistake: When Sheldon goes to Penny's apartment and they do a scene study together, they both read lines from a multi-page script that Sheldon brings with him. On a couple of occasions the camera cuts to a side view of Sheldon and we get to see the page of the script that he's currently reading from. The pages are completely blank.

The Herb Garden Germination - S4-E20

Revealing mistake: When Sheldon is web chatting with Amy, we can hear Amy talking, but the bar at the top of Sheldon's computer screen indicates that the sound is off.

The Peanut Reaction - S1-E16

Revealing mistake: In the scene where Leonard is supposedly playing Halo 3 against somebody in Copenhagen, there is no ethernet cable or wireless adapter connected to the Xbox 360 (one of the originals without wireless inbuilt), which means that there is no way he can be playing online with someone in another country. (00:09:00)

Show generally

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

The Spoiler Alert Segmentation - S6-E15

Revealing mistake: Throughout the series much is made of the fact that Howard's mother is grossly obese, and in The Engagement Reaction (S4 E23) it is even mentioned that her arms are hugely oversized. However, at the end of this episode we see her arms when she grabs Raj to stop him climbing out of the window, and they are the arms of an average-weight woman - they aren't overweight at all.

The Einstein Approximation - S3-E14

Revealing mistake: In the scene where Sheldon visits Leonard and Penny in bed, towards the end of the scene, Leonard turns off the light. As he does, if you look carefully, you can see that the light turns off before he hits the switch.

The Herb Garden Germination - S4-E20

Revealing mistake: Sheldon's laptop has gone through several strange transformations throughout the series, but in this episode it takes the biscuit - it appears to be a Dell XPS with the back covered up, but the shot of Sheldon chatting only to Amy shows a Mac keyboard, with the laptop running OS X.

Show generally

Revealing mistake: If you look at the marble patterns on the walls, they are all exactly the same from floor to floor. Also the bricks oddities on the stairway match from floor to floor. They change lights, elevator tape etc. but it's the same floor used over and over as different floors.

Revealing mistake: When M.O.N.T.E. crashes through the door at the end, the door hits the wall on the other side of the corridor. The wall shakes, revealing it's a set.

The Gorilla Dissolution - S7-E23

Revealing mistake: After Howard lets go of the unpacked treadmill, it begins to fall down the stairs. As it goes out of frame, the treadmill begins to level itself out, but the sound of it is still heard falling and Howard, Bernadette and Raj continue running past, way further than where it levelled itself out anyway. (00:00:35)

Casual Person

The Killer Robot Instability - S2-E12

Revealing mistake: Near the end of the show, the big robot is chasing the other robot down the hallway. The camera starts to zoom in as the robots come by it. The big robot stops just before the camera zoom is past it, yet they keep running down the hallway like the robot is still going.

The Killer Robot Instability - S2-E12

Revealing mistake: When M.O.N.T.E. crashes through the door, if you watch carefully, the door is already off its hinges and falling before M.O.N.T.E. hits it.

The Hamburger Postulate - S1-E5

Revealing mistake: When Penny leaves when Leonard and Leslie are in his room, she opens the apartment door and the hallway is isn't present. It's just a chipboard wall. (00:09:50)

The Countdown Reflection - S5-E24

Factual error: There is not a snowball's chance of Howard becoming an astronaut. He suffers from cardiac arrhythmia, something about which he is completely open. "Transient" or not this is easily detectable by a simple electrocardiogram, which is a fundamental part of the many medical examinations a potential astronaut will have to pass. He wouldn't even be allowed to start basic training. Note also that during his basic training he shows signs of severe stress and trauma which would inevitably trigger a cardiac episode. Even if it didn't the fact that he was falling apart at the seams would have him removed from the programme for his own good.

Stephen Hawking: Do you like brain teasers?
Sheldon Cooper: Oh, I love brain teasers.
Stephen Hawking: What do Sheldon Cooper and a black hole have in common? They both suck. Neener, neener.

One named "Couples I Like" and the other "Couples You Like." Under the "Couples You Like" column, one of the couples is Blossom and Joey.
