Lt. Columbo and Dale Kingston in “Unfinished Business”

Lt. Columbo

You know that gallery you went to? Checked out. I hope you don't mind.

Dale Kingston

Oh, that's your job. And?

Lt. Columbo

Uh, the parking lot boy, he remembered when you got there, alright. So that if Mr. Mathews was killed at 11:00 you sure didn't do it.

Dale Kingston

Now, isn't that a shame? And here I am your best and most obvious suspect, too.

Lt. Columbo

Ah, don't say things like that. Really, you got me all wrong.
