Columbo, Season 1

Lt. Columbo:
Say, you know the soap you have in the bathroom, the ones shaped like little lemons?

Leslie:
Yes.

Lt. Columbo:
Well, I was almost afraid to use them.

Leslie:
But that's what they're there for, Lieutenant, to be used.

Lt. Columbo:
Well, if you don't mind my asking, when you use one and you put it back in the plate, how do you keep it from sticking to the others?

Leslie:
It's a problem.

Lt. Columbo:
That's what I figured.
