The clip "Don't make a sound!" from Duck Soup (1933) with Raquel Torres, Chico Marx
You gotta the plans?
No, but they're somewhere in the house,
and you must find them. Oh, for Heaven's sake, whatever you do, don't make a sound.
If you're found, you're lost.
You craz', how can I be lost if I'm found?
Got a flashlight?
You don't know how serious this is.
If they catch you, you'll be court-martialed and shot.
I must go before she looks for me.
Now remember, whatever you do, don't make a sound.
You stay here, but keep quiet.
Remember what she said, if we get caught, we're gonna get, uh, court-plastered.
