The Rothman Disintegration - S5-E17
Corrected entry: After Sheldon has told Barry about the rules of Rock/Paper/Scissors/Lizard/Spock for the first time, Barry then replies "I'm sorry, can you repeat that." When he says "repeat", he correctly pronounces the "r." However, it has already been established throughout the series that Barry pronounces all his Rs like Ws due to his speech impediment.
The Wiggly Finger Catalyst - S5-E4
Corrected entry: Five minutes into the show, Sheldon has written down what a dice roll will tell him what to do. He rolls the dice, pauses and looks at the list to see what he has to do for that dice roll. The problem is he has an Eidetic memory and wouldn't take the time to look at the list when he can already see it in his head.
Correction: This is not at all accurate. The list he his looking at is the Cheesecake Factory menu, not one he created himself. Given the nature of the menu page Sheldon looks at, it's unlikely he's ever looked at that page before.
Corrected entry: Leonard and Penny are inhaling Sulphur Hexaflouride to make their voices low. The effect can be seen to be fake for two reasons. First, their voices go back to normal instantly and on demand - the gas actually takes a while to clear. Second, when Leonard releases the balloon, it flies away; it should just fall to the floor because Sulphur Hexaflouride is heavier than air.
Correction: 1. Wrong episode. This scene is from Episode 23. 2. Your voice will clear in as much time as it takes to clear your lungs - one or two breaths. 3. A sulfur hexafluoride balloon will still fly, as the escaping gas is still propelling it, as demonstrated in this clip by Mythbuster Adam Savage http://www.youtube.com/watch?v=d-XbjFn3aqE.
The Transporter Malfunction - S5-E20
Corrected entry: During their discussion about the guest list for Howard's wedding, Raj speaks openly, not only in front of Penny, but sitting next to her. They haven't been drinking.
The Shiny Trinket Maneuver - S5-E12
Corrected entry: After Amy stalks off on Sheldon, Penny tells him off because she told him some good news about her paper being published, and he belittled her achievements while bigging up his own, trivial activities. She is very specific about what he did and why Amy reacted. How did she know all of this? She was nowhere near the table at the time and could not possibly have overheard their conversation. She might assume Amy is mad at Sheldon but she can't possibly know why.
Correction: Penny is behind them cleaning a table and you actually see her overhear what they are talking about.
The Wiggly Finger Catalyst - S5-E4
Corrected entry: In this episode, everyone is surprised to learn that Raj's family is enormously rich, but in episode 15 of season 4 Raj states that his family is wealthy and has lots of servants.
Correction: They knew Raj's father was a well-off doctor, so someone we might call upper class. This episode they found out he was extremely rich, more along the lines of the richest men in the country.
The Hawking Excitation - S5-E21
Corrected entry: Stephen Hawking tells Sheldon he made an arithmetic mistake on page 2 of his paper. Sheldon then quickly turns pages on his paper to find the error, but Sheldon turns several pages of his paper, way past the second page, and still finds the error Stephen had noted.
Correction: Scientific papers number their pages differently to how one would assume. There are pages before page 1 begins which are often numbered using Roman numerals. Therefore Sheldon is correct in turning several pages to find page 2.
The Shiny Trinket Maneuver - S5-E12
Corrected entry: In 3-14 "The Einstein Approximation" Bernadette stated that she is able to easily handle children as her Mother ran an illegal day care centre in their basement. However, in this episode she states that she hates children because her mother worked and she had to bring up her siblings, and she cannot properly react to children. So which is it? Can't be both.
Correction: In 3-14 she says she can handle "stubborn children" and in 5-12 she refers to "little kids". Every parent will tell you there is a big difference in behavior in children at child-care age [i. e. Daycare children] and little kids [a little older]. It is easier to get them to do things when they are small but once they develop their "attitudes", it is very hard to get them to do what you want.
The Countdown Reflection - S5-E24
Corrected entry: When they are marrying Bernadette and Howard, Raj is speaking straight to the women without alcohol. And it's the same people as he normally can't talk around.
Correction: Although no alcohol is shown onscreen, it doesn't necessarily mean he hadn't already drank any alcohol already. There's nothing there to say whether or not he quickly had a drink before the ceremony, off-screen, whilst they were setting up on the roof.
Correction: Barry doesn't always mispronounce the letter R. It can happen with certain Rs and Ls.
