Corrected entry: Robin walks into the apartment and sees a goat turd, which can only be there if the goat was in the apartment. She goes on to talk to Marshall about keeping quiet about the fact that she slept with Barney, so we know that this happened when Ted was turning 30. But later in the end, Ted says that the goat was actually there on his 31st birthday. So the goat turd could not have been there at the time.
Corrected entry: When forced to explain himself to Quinn in 1 minute after finding out Barney and Robin used to date, Barney incorrectly states that Robin moved to Brazil and came back with "a Latin stud" after Ted and Robin broke up. Robin actually vacationed in Argentina. (00:11:35 - 00:12:40)
Corrected entry: This episode takes place during the holidays and Robin is missing her family. At the very end of the episode Robin and Marshall are sitting outside - Robin is eating an ice cream cone and Marshall is drinking an icee, and they are both wearing T-shirts. Behind them are poinsettia plants and they mention Christmas in the episode. They live in New York. It snows in New York during the holidays or is at least cold. They would not be wearing T-shirts sitting outside on the stoop eating ice cream.
Corrected entry: When the gang is thinking about baby names, Esther is brought up. We then see Marshall and Barney at the strip club where Esther shoots out a bunch of playing cards and one sticks to Barney's forehead. He peels it off and says "That WAS my card!" But he never looked at the face of the card, so he couldn't possibly have known which card it was.Knever
Corrected entry: Cindy's claim that there is a policy against faculty and students dating is right, but according to the website of Columbia university it doesn't apply to a relationship between Ted and her. Excerpt from the policy on consensual romantic and sexual relationships between Faculty and Students of Columbia University: "It is the policy of the University that no faculty member shall have a consensual romantic or sexual relationship with a student over whom he or she exercises academic or professional authority."Tanngrisnir
Corrected entry: In S3E15 "The Chain of Screaming" Barney is talking about Gary Blauman confronting his boss, and when Marshall asks, "Is that the end of the story?" Barney replies, "No, no of course not. He died." But in s9e21 the entire episode is about Gary Blauman.Nathan Ehrnsberger
Corrected entry: In this episode we get to see when Ted met Marshall. But in Season 2, episode 1 Ted says to Marshall, "And there was my roommate, lying on the bed with his feet up on the wall. He had headphones on, big smile on his face. That guy was you." In this episode we get to see it was different. (00:04:40)IDFS33140
Corrected entry: In this episode Marshall and Lily buy an apartment that turns out to be crooked. When Marshall is hanging the picture it slants to the left of the camera each time he tries to straighten it, however the apartment is slanted to the right, on camera, and also demonstrated by Robin when she rolls the champagne bottle.
Corrected entry: When the first error in Barney's list is discovered, they come to the conclusion that he's only slept with 198 women, so Marshall's previous figure of a 1.195913451538% success rate is slightly off. Marshall says that Barney's "only half a percent less gross than we thought." But using 198 girls in Marshall's equation results in a success rate of 1.18990461538%, which is nowhere near a difference of 0.5%.Knever
Corrected entry: In the scene where Robin and Ted are talking on the roof at the end of the episode, Robin asks Ted why, when Mike was willing to look like a complete idiot by dressing us as Hansel for her, she couldn't 'be Gretel' to be a good girlfriend. Ted replies, "Because you just haven't met the right Hansel yet". Hansel and Gretel were in fact brother and sister in the story.benson
Corrected entry: There are two problems with the scene in which Heather enters the store with the briefcase. One is debatable, but one is not. All stores, for safety reasons (most notably, if a fire were to break out) should have doors that open outwards, away from the store. It's a law in most areas of the US. The other thing is that Ted says, "That's a "push," not a "pull."" That means that she attempted to pull it, but if it were a "push" door, there would be no handle to pull, meaning there is nothing there for anyone to pull on.Knever
Corrected entry: The mystery woman warns Lily to stay away from Barney Stinson. When they go visit Anna, the second woman on the bracket, Barney reminds Lily that she thinks he's Ted Mosby. That would remove her as a candidate right away since Lily was warned to stay away from Barney, not Ted.
