The clip Breaking in from Duck Soup (1933)
I happen to know...
that Freedonia's plans of war are in Mrs. Teasdale's possession.
I must get hold of them.
Yes, but how?
We have a weekend guest in Mrs. Teasdale's house.
Now gentlemen, do you mind waiting for me outside? I'll join you in a moment.
Yes, I am alone. No, not yet.
Vera, we've got to work fast. You must get hold of those plans tonight.
Chicolini and his partner should be there any minute. Do everything you can to help them.
But I must be very careful. There is another guest in here for the weekend.
Firefly. I don't know, I think he is asleep.
Ring the bell.
Push the button.
