George McFly

"I never realized how important parents are."

"A man can change his destiny."

"I guess you guys aren't ready for that yet. But your kids are gonna love it."

"I can't believe I was ever in love with that girl."

"Maybe we shouldn't have come here. Maybe it's not safe."

"I was afraid to go back in my life, but I did, and it changed everything."

"You know what? I'm calling myself a cab."

"Nice underwear, McFly."

"Why don't you make like a tree and get out of here."

"I'm going to go ask her out."

"It's not my kid. Kid's crazy."

"I think you're my boy."

"I gotta stand up for myself sometime."

"Biff, you leave her alone!"

"I'm your father."

"Some people are just born loser, I guess. But not you."

"I'll come back and visit you guys in 30 years."

"I'm never going back in time again. It's too dangerous."

"Look, I understand what you're going through."

"We got a second chance. Let's make the best of it."

"If I had more guts, I'd go back and push Biff into a lake."

"I believe in myself now."

"Lorraine means everything to me."

"I never thought I'd be this happy."

"A man has to learn to be responsible."

"I'm stronger than I thought I was."

"Don't be afraid to take chances."

"I never knew how good life could be."

"I got my family. That's what matters."

"I've got to face my fears head on."
