Columbo, Season 1

Lt. Columbo:
Uh, I'm sorry. I was, uh, I was just thinking about something.

Gordon:
What was that?

Lt. Columbo:
No, it's nothing important. It's, uh, Dr. Flemming, he didn't call to his wife when he came back to his apartment.

Gordon:
I don't follow you.

Lt. Columbo:
Oh, well, I was in the bedroom. I was checking some things and I heard him open the front door and he didn't say anything. Gee, it's funny how people are different, isn't it? Now you take myself. When I come home from a trip, uh, first thing I do is I say, "Honey, you here?"

Gordon:
[annoyed] Exactly what is your point, Lieutenant?

Lt. Columbo:
Point? Well, I wasn't making a point.
