Ninotchka: [on a street corner] How long must we wait here?



Leon: Well, uh, until the policeman blows his whistle again….



Ninotchka: At what intervals does he whistle?



Leon: What?



Ninotchka: How many minutes between the first and second whistle?



Leon: You know that’s very funny. I never thought of that before.



Ninotchka: You’ve never been caught in a similar situation?



Leon: Yes, I have, now that I’ve come to think about it. It’s staggering. Good heavens. If I add it all up, I must have spent years waiting for signals. Imagine, an important part of my life wasted between whistles.



Ninotchka: In other words, you don’t know.



Leon: No.



Ninotchka: Thank you.



Leon: You’re welcome.
