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.

Continuity mistake: In the scene where Lily and Marshall are talking outside the bar, the same extra (a guy in a blue plaid shirt with a denim shirt over the top) walks past Lily twice, going in the same direction both times.
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).
Continuity mistake: In the scene at the hotel bar, the red straws lying on the table next to Ted change position between shots without being touched.
Continuity mistake: In the scene at the bar where Robin is describing looking after Marshall as being like having a baby, Barney's drink moves from in his hands to on the table and back again instantly between shots. (00:06:30)
