Continuity mistake: When Barney and Ted are calling dibs on the girl at the bar, in the closeup her book cover clearly reads "Brideshead Revisited", but in the wide shot it's something else entirely, spread across several lines.
Continuity mistake: There is a lot of foam in the glasses when Barney pours champagne, however after camera shot changes all the foam is gone. (00:10:15)
Continuity mistake: Randy's noise bleed moves from his left nostril to his right and then back again. (00:14:20 - 00:15:00)
Continuity mistake: When Randy reveals that he didn't sleep with Robin, the blood from his nose switches nostrils between shots.
Continuity mistake: When Ted leaves the bar he leaves his phone behind and yet he somehow still makes a phone call to Lily from the subway.
Suggested correction: Depending on the location settings on his laptop, they could be giving a false reading. My laptop shows I'm in Cardiff Wales while in fact I'm nowhere near.

The show was actually filmed on a film set in Los Angeles which is probably why the laptop says Los Angeles as the current location. This most probably slipped past the editing crew.
