Mary: George, I didn't know you could yodel.
George M. Cohan: Learned it on the farm. Nothing but pig callin' with frost on it.
George M. Cohan: Thanks, Sam. It'll be great as long as those critics don't start to eat off my leg.
Sam Harris: Oh, don't worry about the critics! You got a smash hit! It's in the air, kid! It's in the air! You can't stop anything that's in the air.
George M. Cohan: My mother thanks you, my father thanks you, my sister thanks you, and I thank you.
George M. Cohan: It seems it always happens. Whenever we get too high-hat and too sophisticated for flag-waving, some thug nation decides we're a push-over all ready to be blackjacked. And it isn't long before we're looking up, mighty anxiously, to be sure the flag's still waving over us.
George M. Cohan: Being versatile, I played my mother's father.
