DS Rycott: Being a police officer is a 24-hour-a-day operation. Villains don't work to a timetable.
DC Jones: They do if they're planning a train robbery.
[Arthur turns up a few minutes late to visit Terry in prison, just as a guard is shutting the door]
Arthur Daley: Ah! Too late, am I?
Prison Gatekeeper: No. We let almost anyone in. It's getting out again that you've got to worry about!
[after they have had a major argument, Arthur finds Terry working as a gardener for Colonel Caplan]
Arthur Daley: Here, what size boots do you take?
Terry McCann: [looking puzzled] Eight.
Arthur Daley: Tread on that, will you.
[Arthur throws his cigar butt out of the window and drives off with gravel flying from his wheels]
