- Why, you've got to believe it. What can I do? What will do to prove to you I'm not lying?
- Anna, would you...? Would you be willing to swear an oath, a terrible, fearful oath?
- Oh, sure, I will, Matt, on anything.
- Give it to me. What do you want me to swear? You say it.
- Swear I'm the only man in the world ever you felt love for.
- I swear it. I swear it by God.
- And may the blackest curse of God strike you if you're lying.
- And may the blackest curse of God strike me if I'm lying.
