Nicely done, both are correc!

#6 is Lawrence Melville in Identity Crisis.

And #4 is Luis Montoya in Matter of Honor
and I think #1 is Prescription Murder - I think it was Ray Fleming to Burt Gordon (or was it Burt Gordon to Ray Fleming??)

correct on Melville and Montoya, not so correct on Dr. Fleming!

the two remaining answers are harder because they are from the later episodes, I'll give you all a little more time before I give it away.

Are you talking post 70's? There's my problem then, I've only seen those 2 or 3 times each, not 50:)

ha ha that sounds about my ratio!

Yes, they are both post-70's episodes. #1 is Congressman Mackey to Oscar Finch in "Agenda for murder". #2 is the male killer to the female (played by Shera Danese) in "A trace of murder".

Thanks all for playing!

Thank you! That was fun!

Yes it was - here are a few more to keep it going:

1. "Hook, line and sinker"

2. "That is the prevailing theory"

3. "5 years . . . 6 months . . . 1 day . . ."

4. "Lieutenant! I'd like an explanation."

5. "I talk better when this is lit"

and for extra credit:

6. (grimacing facial expression) "He sure is." (HINT: quote #4)

These are good, have to think about them, but quickly know that #5 is from Try and Catch Me, when Columbo is talking to the women's group.

Irene you're correct on #5

#4 is the guy from the Winston Insurance Company, in "Identity Crisis". #6 is a woman at the carnival that Columbo showed the picture of dead Geronimo to.

Correct on 4 and 6

"Hook, line, and sinker" is from "Dagger of the Mind".

yes
