"I'm your density. I mean, your destiny."

"Make like a tree and get outta here!"

"You're my favorite girl, McFly."

"I own the past, present, and future of this town."

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
