Uncle Billy
- George Bailey: [George hears a train whistle] There she blows. You know what the three most exciting sounds in the world are?
- Uncle Billy: Uh huh. Breakfast is served; lunch is served; dinner...
- George Bailey: No no no no. Anchor chains, plane motors and train whistles.
- George Bailey: [the staff celebrates closing the building and loan company with only two dollars remaining, to stay in business] Get a tray for these two great big important simoleans here.
- Uncle Billy: We'll save 'em for seed.
- George Bailey: A toast! A toast! A toast to Mama Dollar and to Papa Dollar, and if you want to keep this old Building and Loan in business, you better have a family real quick.
- Cousin Tilly: I wish they were rabbits.
- Uncle Billy: After all, Potter, some people like George HAD to stay at home. Not every heel was in Germany and Japan.
- Uncle Billy: [drunk] Where's my hat? Where's my hat?
- [George takes it off Billy's head and hands it to him]
- Uncle Billy: Oh, oh thankyou, George. Which is mine?
- George Bailey: The middle one.
- Uncle Billy: They're putting us out of business. So what? I can get another job, I'm only 55.
- Cousin Tilly: 56!
- Harry Bailey: Uncle Billy, you haven't changed a bit.
- Uncle Billy: Nobody ever changes here, you know that.
- Uncle Billy: On boy, oh boy, oh boy, oh boy! I feel so good I could spit in Potter's eye! I think I will, I think I will!
- Mr. Potter: [Harry's won the Congressional Medal of Honour] How does slacker George feel about that?
- Uncle Billy: Very jealous, very jealous. He only lost three buttons off his vest.
- George Bailey: Did you put the envelope in your pocket?
- Uncle Billy: Maybe, maybe, maybe.
- George Bailey: Maybe, maybe! I don't want any maybe, look we've got to find that money.
