Bilbo
"Thank you." Bilbo says to the woman, both for the alcohol and the pipe-weed. He turns to the man and says, "My name is Bilbo Baggins, sir, of the Shire. I can sneak into anywhere and get out with anything. I can find out plans, steal items, and kidnap commanders." Bilbo subtly shifts his hand towards his pocket, and effortlessly slips on the ring. As he turns invisible he says, "See? Sorry, actually. I guess you wouldn't."
