The Genie in "Aladdin," 1992

"But, oh, to be free! Not to have to go 'Poof! What do you need?' 'Poof! What do you need?' 'Poof! What do you need?' To be my own master. Such a thing would be greater than all the magic and all the treasures in all the world! But what am I talking about? Let's get real here, it's not gonna happen. Genie, wake up and smell the hummus."

Daniel Hillard and Mrs. Doubtfire in "Mrs. Doubtfire," 1993

"I just want to know one thing. Are your kids well-behaved? Or do they need, like, a few light slams every now and then?"

Sean Maguire in "Good Will Hunting," 1997

"You will have bad times, but they will always wake you up to the stuff you weren't paying attention to."

John Keating in "Dead Poets Society," 1989

"We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion. And medicine, law, business, engineering. These are noble pursuits and necessary to sustain life. But poetry, beauty, romance, love -- these are what we stay alive for."

Peter Banning in "Hook," 1991

"To die would be a grand adventure!"

Adrian Cronauer in "Good Morning, Vietnam," 1987

"You know, Eddie, sometimes you got to specifically go out of your way to get into trouble. It's called fun. What's that? Come on. Take some chances once in a while, Edward. That's what life's all about."

Parry in "The Fisher King," 1991

"There's three things in this world that you need: Respect for all kinds of life, a nice bowel movement on a regular basis, and a navy blazer."
