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."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
