"Let's be careful out there" - Expression of concern directed to fellow officers by Sergeant Phil Esterhaus (Michael Conrad) at the end of each daily roll call on the police drama HILL STREET BLUES/NBC/1981-87. When Michael Conrad died, his character's phrase "And, hey! Let's be careful out there" was replaced by the more pessimistic "Let's do it to them before they do it to us" spoken by Esterhaus' replacement Sergeant Jablonski (Robert Prosky).
