George McFly: "If not for him..."

Lorraine McFly: "... we would never have fallen in love."

George: "There was also that strange boy, he kept um, matchmaking us, pushing me so hard toward you."

Lorraine: "Oh yes! Would you believe it? Dad hit him with the car! He seemed so strong, so self-assured, so confident. So quick to brush off being hit by a car. And then so quick to stand up to Biff and the bullies for me--" Glances over at George. "Both of us, such a knight in shining armor! I just couldn't help falling hard for him."

George: "And then he disappeared. He promised -- guaranteed in fact -- that we would see him again. But we never have, and it's been thirty years and counting."

Lorraine: "I'm not so sure. You wouldn't by any chance know anything about this, would you, Marty?"

Marty: "Huh?"

Lorraine, with a cock-eyed glance and grin: "Or should I say, Calvin Klein?"

Marty flushed and froze in embarrassment, unable to articulate for a moment. He finally said, "Mom! You knew?"

Lorraine, smiling: "Of course I knew. I am your mom." She turned serious. "My only question was when would it happen for you. First thing now, we take you to the hospital and check you out for internal injuries."
