Continuity mistake: When Jay is sitting in the patrol cart with his partner eating ice-cream, the amount of the partner's ice-cream that has melted keeps changing from shot to shot. Sometimes the ice-cream has melted a little bit, sometimes it has melted over his fingers, sometimes it hasn't melted at all. Jay's ice-cream also changes just as often, but is not as obvious.
