Rachel Shelley, who plays a ditzy valley girl horrifying the British characters, is British in real life.
Matt's car's license plate, California 2ABM543, resembles a sequential plate that would have been issued in 1986 or 1987, although his car is obviously a new model in 2011, when the series was filmed. In California, sequential plates belong to the car, so are not moved to new cars (unlike personalized plates, which can be transferred to a new car).
2ABM543 is a plate often used in movies and television shows and is not a valid plate.
