Lady and the Tramp (1955)
Jock: Look here, laddie! Who are you to barge in?

Tramp: "Stop that racket, you'll wake the baby!" And then... then they hit you on the room and board department. Oh, remember those nice, juicy cuts of beef? Forget 'em. Leftover baby food. And that nice, warm bed by the fire? A leaky dog house.
Lady: Oh, dear!
