You're right, Cass. The "loco" one is from "A Matter of Honor." It's the response to Columbo's having said that he has the occupational hazard of taking his work everywhere he goes.

The one about being back on schedule is said by Kay Freestone to the filming crew at the carousel location. She rips out part of the script to get them back on schedule just before she is fired and then nailed by Columbo.

good one laura on the script thingy from make me a perfect murder....good job!!

the knock at the door was from "Murder, a Self Portrait." It was the beginninhgs of all of Louise's nightmares. That was a good one Fred, really made me think
