Quote from : The Hobbit: The Desolation of Smaug Movie

Gandalf: [talking inside The Prancing Pony] I ran into some unsavory characters whilst traveling along the Greenway. They mistook me for a vagabond.
Thorin Oakenshield: I imagine they regretted that.
Gandalf: One of them was carrying a message.
[Gandalf puts the message on the table]
Gandalf: It is Black Speech. A promise of payment.
Thorin Oakenshield: [looking at the message] For what?
Gandalf: [looking at Thorin] Your head.
