The Gorilla (1939)
Kitty: Why couldn't all of this have happened tomorrow?
Norma Denby: What difference would that make?
Kitty: Tomorrow's my day off!
Mulligan: First time I saw a mousetrap catch a piece of cheese!
Peters: Did I hear somebody scream?
Kitty: Well, if you didn't, you oughta have your ears cleaned out!
Jack Marsden: Why is it something always happens when YOU'RE not here?
Peters: Unfortunate coincidence, sir.
Kitty: The Gorilla? HIM? Oh, I'll never trust another man if I live to be a thousand!
[at a huge crash from the cellar]
Jack Marsden: Peters, what's all that commotion?
Peters: It sounds like our friends the detectives.
