After viewing the movie, Det. Sgt. Arthur Dietrich answers the phone and says "yeah hold on a second", he presses a button to place the call on hold and then tells Barney it's the deputy commissioner's office, hands Barney the receiver and Barney starts the conversation without ever taking them off hold.
- This is incorrect. Dietrich puts the call on hold, hands Barney the phone, and presses the button just before Barney speaks.
