Columbo: Mrs. Peck? Mrs. Peck, I made a very poor introduction of myself to you, I know that. I'm a stranger in your house that you love and I'm here to do something that's not very pleasant, so I don't expect you to like me but I have feelings too, Mrs. Peck. Now, I'm sorry about being untidy. That's something that I can't control. That's a fault of mine that I-I, I don't know, I just can't correct that, and I've tried many years. I'm just very untidy. That's my nature, but I've never been un... I-I-I've never been rude to you, Mrs. Peck, and-and i-if you keep on treating me like an enemy just because I'm here trying to find who killed a man that you worked for for thirty-three years, well, then... well, then I think you're a very unfair person.
Mrs. Peck: Bum! You're a bum! Putting your stinking cigar butt in this silver antique dish! D'you see this?
Columbo: I thought it was an ashtray. I have one at home that looks exactly like that.
Columbo: Would you mind very much coming with me into the bathroom?
Norman Paris: You got the Degas. I got the Picassos.
Dexter Paris: [Derisively] Norman, you couldn't tell Picasso from a Rorhshach test!
Norman Paris: Can anyone? I know very much what they're worth.
