Corrected entry: When Sheldon and Barry are rock climbing, Sheldon looks down and shouts in fear. When Barry asks "You all right there Cooper?", Sheldon answers "I feel somewhat like an inverse tangent function approaching an asymptote." An inverse tangent function approaches its asymptote in the horizontal axis, not the vertical. (00:15:55)
Corrected entry: For being smart they act stupid here. They don't think to alter the days the guys use the parking space with Friday being where they either share it together or Leonard or Raj get it while Howard and Sheldon would each get it two days apiece.
Corrected entry: At the end of the episode Sheldon's sat nav voice asks "Can you name the four state capitals that are not served by the interstate system?" In fact, there are five, according to the Interstate System's website. Juneau, Alaska; Dover, Delaware; Jefferson City, Missouri; Carson City, Nevada; and Pierre, South Dakota.
Corrected entry: The "Hollermus" that Sheldon allegedly makes is not actually a Swiss breakfast dish. It is in fact simply a kind of jam made from elderberries which is quite common in most German-speaking countries. Also, judging by the ingredients on the table (eggs, milk, butter) and the food on the plate, the dish prepared by Sheldon seems most likely to be an omelette with a Vienna sausage, which is in no way traditionally Swiss.
Corrected entry: Professor Crawley states he discovered a new species of dung beetle (named after him) in a rain forest in Borneo. That is impossible - dung beetles do not live in damp climates as the fecal matter upon which they live degrades too quickly when moist. You can find dung beetles in Savannah grassland, semi-arid desert, some lightly wooded areas, but a rain forest? Never.
Corrected entry: At the end of the episode, Sheldon runs off to Texas. That would be impossible in the short time frame the episode was set in. Especially since they live in Pasadena, California. California is 18 hours away by car from Texas. It has also been stated previously that Sheldon dislikes cars and airplanes a lot.
Corrected entry: Dr. Ramona Nowitzki returns and Sheldon introduces her to everyone as if they have never met her but, outside of Amy and Bernadette, they did years ago back in season 2. At the very least Leonard and Penny should remember her. But no-one acts like they do.
Corrected entry: Wil Wheaton tells Sheldon that he missed the convention because his grandmother died. When Wheaton later refers to a living grandmother, Sheldon realizes he has been tricked. He shouldn't - presumably Wheaton, like everyone else, has two grandmothers (mother's and father's side) and thus Wheaton announcing he has a living grandmother in no way contradicts what he said before. This alone shouldn't tip Sheldon off that Wheaton was lying.
Corrected entry: Sheldon asks Missy why she doesn't tell her friends that he is a toll taker on The Golden Gate Bridge. There are no toll takers on the Golden Gate Bridge. Tolls are paid by credit or debit card, a prepaid account or by invoice to the registered car owner's address. There is no way Sheldon would not know this.
Corrected entry: Penny got a red light camera ticket while Sheldon was driving her car. She says she gave up Sheldon as the driver to the court because she didn't want to get any more points on her license. You don't get points on your license for a camera issued violation. The registered owner just gets a straight fine. A police officer has to issue a ticket at the scene to get license points.
Corrected entry: When the guys are locked in the basement, the door hinges are on their side. You would think a theoretical physicist, experimental physicist, astrophysicist, and NASA engineer could together figure out to simply take the pins out of the hinges.
Corrected entry: Several times throughout the show, Leonard makes reference to having sleep apnoea, a condition where the airways close up when you are asleep and you stop breathing for periods of time before your body's reflexes kick in and wake you up. However we also see him sleeping numerous times but he doesn't have any form of cpap (Continuous Positive Airway Pressure) machine. This is vital for anyone who has sleep apnoea as it pumps air into the users airways via a nasal cannula or face mask to keep the airways open and stop the user from stopping breathing. Since sleep apnoea in the most extreme cases can cause death (depending on type of sleep apnoea) a cpap machine is vital and should be seen whenever we see Leonard sleeping or in bed.
