Here are two examples.
- Our Gang short Shiver My Timbers:
The ship captain (Billy Gilbert) growls at a crew member: “What are you two doing over there?”
The crewman (Harry Bernard) answers, “We don’t know, captain.” - Early on in Some Like It Hot, Sweet Sue (Joan Shawlee) says “My sax player runs off with a Bible salesman and the bass fiddle [player] gets herself pregnant!” (Gets herself pregnant?! I’d sure like to know how she did that!)
Post your own examples of an astonishing line.
