TV Quote of the Day (‘Columbo,’ On Detectives’ Advantage Over Murderers)

Lt. Columbo [played by Peter Falk] [addressing psychiatrist Ray Flemming—an as-yet uncaught killer]: “You know, cops, we're not the brightest guys in the world. Of course, we got one thing going for us: we're professionals. I mean, you take our friend here, the murderer. He's very smart, but he's an amateur. I mean, he's got just one time to learn. Just one. And with us, well, with us, it's—it's a business. You see, we do this a hundred times a year. I'll tell ya, Doc. That's a lot of practice.”—“Prescription: Murder” (pilot for the Columbo series), original air date Feb. 20, 1968, teleplay by Richard Levinson and William Link, directed by Richard Irving
