The Chain Of Screaming - S3-E15
Continuity mistake: When they're all sitting in the car listening to Marshall's story, Robin's ice cream changes between shots.
Sandcastles in the Sand - S3-E16
Continuity mistake: When Lily goes to the bar with her friend Michelle, Barney says "I want her around all the time." It then cuts from Barney to Lily's slightly shocked looking face, obviously from a previous cut/scene change, sitting at the table with them - she should still be walking to the bar with Michelle.
Suggested correction: Those were different days. Robin agrees to watch Simon's practice before we see Michelle the first time, then the scene cuts to Robin watching the band practice, then the news feed and then the next scene with Michelle. All the character's clothes changed indicating a different time.
Continuity mistake: When Lily is selling her favourite dress and is saying how she got a two syllable damn, the flashback shows her with the hairstyle she got after Coming Back from San Francisco, even though she said it happened in 2004. She should have had her shorter, lighter coloured hair. (00:15:10)
Continuity mistake: In Ted's flashback where Barney's mysterious saboteur is talking to Lily, the girl has straight blonde hair. In episode 14, "The Bracket" where his saboteur was first introduced and she originally spoke to Lily, she had curly blonde hair in the same sequence.
Continuity mistake: When Robin buys Lily's "favorite dress", Lily holds it on her lap folded, when the camera changes angles it is unfolded.
Continuity mistake: When Barney and Abby are lying in bed after the Local Art Cafe scene, Abby's arms/hands change positions between shots.
Other mistake: Right before Barney gets hit by the bus, he's on the sidewalk. To the right there is a One Way sign pointing right, but the bus hits him driving left. The bus would have been driving the wrong way on a one way street.
Suggested correction: Not only is this not a mistake (it wouldn't be the first vehicle going the wrong way down a one way street), but we even see Barney looking in the direction of where the vehicles should be coming from and assume himself to be safe. Had the bus not been going the wrong way, Barney would have seen it coming and not been hit.
This is irrelevant. The mistake is that the bus is going the wrong way on a one - way street. While people do break the law like this, a bus driver certainly wouldn't.
The Best Burger in New York - S4-E2
Continuity mistake: When Ted picks up his burger it already has a bite taken out of it, then in the next shot the burger is whole again. (00:20:09)
Intervention - S4-E4
Continuity mistake: After the gang gets to the bar around the end of the episode, Ted starts his speech about how they all need to move on. As he moves over to the booth, he tells the people sitting there to get out. You can see that the girl takes her phone with her, and there is no other phone anywhere on the table. A few seconds later, she comes back saying that she left her phone, and now the phone is visible on the table. (00:19:25)
Intervention - S4-E4
Continuity mistake: In this episode, both Ted and Marshall mention that Lucy, Stella's daughter, is 7 years old, when in the previous season (13th episode of 3rd season, Ten Sessions) Stella states: "I have a daughter. Her name is Lucy, she's 8." Did she grow younger?
Intervention - S4-E4
Revealing mistake: In the flashback when Ted damages the ceiling beam with the flail, you can see that the damage is already there before Ted actually hits it.
Intervention - S4-E4
Revealing mistake: When the encyclopaedia bookshelf falls off the wall in the flashback, you can see the wall being pushed out, showing that it was being manipulated from the other side by crew.
Intervention - S4-E4
Continuity mistake: In this episode we see that Barney punched a hole in the wall next to the door because Ted broke apart a girl fight. It is supposed to be under the calendar on the right side of the door. It is also said that Ted and Robin were dating at this time. But earlier, in the episode "Wait For It..." (3-1) We see Ted going through his break up phase after Robin. One of the phases is painting the apartment, and there is no hole.
Continuity mistake: Robin says she never played any team sports in 1-6 "Slutty Pumpkin". But in this episode she talks about her relationship with her father, being on a hockey team that won a championship and she made out with her teammate.
Revealing mistake: In the front shot of Ted in front of Stella's apartment, it is painfully obvious that he is in front of a green screen and not actually on a street.
Other mistake: At the end, on the steps in front of Stella's apartment, Stella's daughter stares at the camera for half the shot.
Continuity mistake: When Lily is making her list she takes the lid off the pen twice. (00:09:00)
Continuity mistake: When they call Barney to find out if he succeeded with The Naked Man, the girl answers the phone. In that shot Barney's tie is curled up next to the shirt, but in the next shot, the tie lies on the shirt. (00:19:00)
Audio problem: When the woman catches Barney doing The Naked Man, she yells at him to get out. After Barney says "Just have to grab my suit, it's very expensive", she says "Get out!" twice. When she says it the second time, she quickly turns her head and her mouth doesn't seem to move with the audio. (00:19:10)
