Biff Tannen

"That's a nice little future you've got there, McFly. Shame if anything happened to it."

"I didn't get where I am by being nice."

"Success is what matters, and I've got plenty of it."

"I'm not afraid of anyone or anything!"

"This is how the strong separate from the weak, McFly."

"I'm gonna be somebody important someday!"

"You should be ashamed of yourself, McFly!"

"I'm the future, McFly. Better get used to it."

"Everything always works out for Biff Tannen."

"I'm not done with you yet, McFly!"

"That's just how the cookie crumbles when you're not as smart as me."

"I've paid my dues and earned my place at the top."

"Make like a tree and get outta here!"

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

"Nobody calls me chicken!"

"You're my dad. I mean, you're my old man."

"I'm gonna be the most powerful man in Hill Valley, and I'm gonna clean up this town."

"Get a job, McFly!"

"Why don't you make yourself useful and get me some coffee."

"I own the police, I own the mayor, I own Hill Valley."

"You're my boy, George!"

"That's what I like about these high school chicks, man. I get older, they stay the same age."

"You McFlys have no spine."

"Everything in life is about money and power."

"Persistence is the key to success."

"I didn't become who I am by taking orders."

"Fear is weakness."

"I make my own rules."

"Winners don't back down."

"You gotta have confidence to succeed."
