Continuity mistake: When Marshall and Ted are on the phone to one another, the string from Ted's hoodie changes position between shots, much of this may be because he is moving his hand due to being on the phone. However the right string goes back and forth from being caught on the collar of his jacket to hanging straight down over his jacket just before he is on the phone to his mother.

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.
