Quote by Biff Tannen

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

"Make like a tree and get outta here!"

"Nobody calls me chicken!"

"You're my favorite girl, McFly."

"I've seen a lot of things in my time."

"That's how we archaeologists tell time."

"We must learn from history or be doomed to repeat it."

"Every artifact tells a story."
