Continuity mistake: When Schmidt and Robbie are spying on Cece's date, Schmidt sits down at Robbie's table to his left and after they both admit that they are still in love with her they bring it in for a hug. Cece walks over to confront them and they are still embracing each other, but they have suddenly switched places and Schmidt is on the right and Robbie is on the left.
Revealing mistake: In the pilot, the exterior of a bar is shown as a scene transition. While the show takes place in Los Angeles, the bar and street intersection shown are in Providence, Rhode Island. You can see a banner with the word Providence in the shot and the street names match the intersection.
