First Time In New York - S2-E12
Continuity mistake: At the airport, Lily and Robin are talking off to the side away from others. During the scene, the cameras shoot from in front of the two actors and from behind Lily. From the frontal view, Lily's two headbands are white and gold-jeweled. The white headband is closest to her forehead. When the camera shot switches from front to behind, the headbands are switched on her head. The gold one is now closest to her forehead and the white one is behind.
Suggested correction: If you look closely, you can see that the headband is actually symmetrical, so the black strap is on top and in the middle of a larger white headband and never changes. (camera angle makes it often seem both from the front as from the back as if there is no white part behind the black).
First Time In New York - S2-E12
Continuity mistake: When Robin is talking to her sister Katie in the Empire State Building lobby, Katie's bag moves between shots. Sometimes she wears it with the strap hanging straight down from her shoulder, in other shots the strap goes across her chest like a messenger bag.
Continuity mistake: When Ted sits down to talk with Hammond Druthers after discovering that Druthers is living at the office, Hammond pours them both a J. Buckley whiskey. When Hammond places the bottle down the label is facing towards Ted. The camera then swaps to Ted and upon swapping back to Hammond, the label is facing away from Ted. Hammond is describing his wife as "quite mannish." The camera swaps to Ted. Upon swapping back to Hammond, when he continues with "She gives me what I need", the bottle has been rotated so that the label faces towards Ted again. (00:11:40)

Monday Night Football - S2-E14
Continuity mistake: In the classroom, Marshall squirts juice on to the boy's clothes then puts the juice pouch flat on the table. In the next shot, the pouch is standing upright.
Continuity mistake: In this episode we learn that Barney doesn't know how to drive. But throughout the whole series there are reference that he actually does, such as: In 'Come On' (22nd episode 1st season) : Penelope says to Barney: "We had sex twice in your car." In 'Moving Day' (18th episode 2nd season) : Barney drives away with Ted's rental van. In 'The Bracket' (14th episode 3rd season) : Barney stole Holly's SUV as they were camping.
Suggested correction: This has been corrected before. Barney does not know how to drive at the time of the subway strike in 2005, but does learn how to drive at some point shortly after that. And it's not until Moving Day (the very episode after this) that we see Barney driving. He does not have to drive in Come On, he just has to own a car.
Moving Day - S2-E18
Continuity mistake: In the final scene when Barney is reading his top ten list, the piece of paper moves from his left to right hand and back in an instant between shots,.
Continuity mistake: In the car, just after Barney discovers they are not headed for Atlantic City, the DVD screen that has been hanging down from the car roof is suddenly stowed away between shots.
Continuity mistake: When Lily's mother is looking at the gift Lily has just opened, the blue bow on the gift vanishes and then reappears between shots.
Continuity mistake: When Ted is giving up with Marshall's best man speech he is holding a pen in his hand as well as a beer bottle. In the next shot the pen disappears and he is just holding a beer bottle. In the next shot the beer is on the coffee table and Ted drops the pen onto the coffee table.
Continuity mistake: In the scene when Lily yells at Robin, because Lily thinks her wedding is ruined, her hair changes. When Lily screams "Of Course I'm not okay." there's only one stray of hair hanging over her left shoulder, but a few seconds later when she screams "Oh grow up Robin." much more hair is hanging over her shoulder.
