Corrected entry: For an obsessive genius Sheldon makes a stupid mistake when he blackmails Leonard into signing a new roommate agreement - any contract signed under duress is invalid. He gains nothing from Leonard signing the new agreement as no other action on his part is required. Effectively Sheldon has got his autograph. Big deal. Leonard is free to ignore the new agreement if he feels like it - and his lawyer was there to witness the fact that he was forced against his will to sign in the first place. This also begs the question of why Priya gets in such a panic about Sheldon blackmailing Leonard by threatening to reveal details of their relationship to her parents - why didn't she just advise Leonard to sign on the dotted line, explaining later that he signed an invalid contract? It would certainly have saved her a lot of grief.
Corrected entry: Howard explains the ease with which he "borrowed" the programmable robot arm thus : "You just have to take it out to your car as if you own it". Howard doesn't have a car - he has a Vespa scooter, and there is no way he could carry the robot arm on that. (While we are on the subject, how does he transport it from Sheldon and Leonard's apartment to his house?).
Corrected entry: Sheldon makes fun of Leonard's idea to go to Raj's for dinner by speculating that they could stop using the letter M, which would be "isguided and oronic. Later he says that "This is adness. Complete and utter adness. He should have said "This is adness. Coplete and utter adness., leaving the M out of the word "complete" - and there is no way a pedantic, obsessive genius like Sheldon would make a mistake like that.
Corrected entry: The proposition that danishes wouldn't exist if Copenhagen were flooded is wrong, because "danishes" were created by Austrian bakers. They are called danish in English-speaking countries because they're very popular in Denmark. The Danish word for this pastry is wienerbrød, which translates to "Viennese bread."
Corrected entry: Sheldon is playing an online game he found. He yells to Leonard "I'm trapped in quicksand, the axe is dragging me down." Leonard then tells him to "Drop axe." Shortly after, Sheldon heads to bed, but he comes back saying "I know how to get the bucket. I can turn the axe around and use the handle to reach it." However, he does not have the axe as he has already dropped it. (00:06:05 - 00:07:45)
Corrected entry: Sheldon steals the 35mm movie canisters and 2 exterior metal cases for "Raiders Of The Lost Ark" so that they supposedly could see it at a later date. We then see Sheldon running with the movie canisters and cases. That would not even be remotely possible as the 2 sets of film weigh approximately 140-160 pounds. Each individual reel (of which there would be a total of 4) has a weight of somewhere between 30 and 35 pounds including the film and individual canister. If you add in the weight of just 2 canisters plus the carrying cases they come in, that's well beyond Sheldon's carrying capacity.
Corrected entry: Sheldon gets Leonard to read the roommate agreement, and it talks about robots. Sheldon is not a robot, he's using a Virtual presence device, therefore Leonard is under no obligation to follow the rules of the roommate agreement. (00:13:10)
Corrected entry: When the characters are driving in the car during this episode, it looks to be a black car (when they film in front of the car). When they run out of gas, there is a shot of them pulling over. The problem is, the car is white when pulling over.
Corrected entry: At the end of the show Sheldon states on the walkie-talkie, "I spy with my little eye, a ferrous metal," Later he reveals that what he spied was the aluminum rims of a police car. Aluminum is a non-ferrous metal - definitely not a mistake Sheldon would make.
Corrected entry: Bernadette tells Howard that she chose the premature ejaculation project because neither of them has any heart diseases. However Howard has stated more than once that he has transient idiopathic arrhythmia. Also in the previous episode he actually emphasizes that his family has a history of heart diseases and alludes to a cave painting showing one of his ancestors clutching their chest.
Corrected entry: At the end of the episode, when Sheldon imagines going to the Grand Canyon to scream about Leonard, that's not the Grand Canyon, signs not withstanding. The location is Dead Horse Point State Park in Utah (near the town of Moab), with the view looking roughly south into Canyonlands National Park. [GPS near 38°28'12" by 109°44'30".] It's several hundred miles upriver from the Grand Canyon. [At least it is along the Colorado River.] The first national park sign looks authentic, but the small one at the overlook is fake, since that's not the Grand Canyon. And by the way, since it's just after New Year's, there would likely be snow at both the Grand Canyon and Dead Horse Point; the images used are not winter scenes.
Corrected entry: If Howard can hack into Blizzard's database so deeply that he can get the name and address of game players, he could easily restore all of Sheldon's stolen 'items'. Hacking personal details - a player's real identity and their home address! - is hardcore, detailed work that only an expert could do, compared to which adding a few extra items to a player in the game would be child's play. Sheldon would not be concerned about a possible comeback from the administrators at Blizzard. First, Sheldon doesn't hack into the database, Howard does, and someone as pragmatic and self-centred as Sheldon would simply disclaim any responsibility. Second, hacking into another player's account to access highly sensitive personal information like their home address would risk incurring the same penalty from Blizzard anyway. Either Sheldon doesn't know that or he doesn't care. Third, his account has already been hacked when the virtual items were stolen. He could simply claim that Howard's hacking into his account was just more of the same - nothing to do with him. Fourth, Blizzard did not detect the hacker stealing Sheldon's virtual items, nor did they prevent it happening, and they did not detect Howard hacking into his account to obtain his name and address. Sheldon can rightly assume he has nothing to fear.
