Quote by Doc Brown

"This is heavy."

"There's that word again, 'heavy.' Is there something wrong with the Earth's gravitational pull in the future?"

"Great Scott!"

"If my calculations are correct, when this baby hits eighty-eight miles per hour, you're gonna see some serious shit."

"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."
