Columbo, Season Six

Ward Fowler:
You think she was murdered, don't you?

Lt. Columbo:
I, I beg your pardon, sir?

Ward Fowler:
You heard me.

Lt. Columbo:
Yes sir, I did. Uh, I mean, yes, I do think it was a premeditated killing, sir. I mean I think the robbery was staged to cover up the murder. Um, how did you know, sir?

Ward Fowler:
Why else would you be here?

Lt. Columbo:
It could be just a routine check, sir.

Ward Fowler:
No, Lieutenant. They don't send a police detective stumbling around, asking silly, fake, innocent questions on a routine check. I know that from my show.

Lt. Columbo:
Silly, fake, innocent questions, like what, sir?
