Not a movie but, Home Improvement (quite a few):
Randy(oh,so hot!): "Let me get this straight. Mark gets fewer rules because he's a dork, and I get more rules because Brad's a dork"
Mark: "So, how is Puerto Rico?"
Randy(Again,Oh,so hot!): "Costa Rica!"
Mark: "Oh, so i guess you didn't get my letters"
Randy: "Did you rebel against your father?"
Tim: "He died before I could be a real jerk."
Randy: "He'd be proud if he could see you now."
Randy: [there is a snake in the light fixture] "Come on, Dad, just stick your finger in the light. When the snake bites it, pull him out."
Tim: "Ha ha ha. Can I talk to you a minute? Maybe you didn't hear ol' Dad the first time: Shut Up!"
Tim: "When you get older, you'll understand not everything is so cut and dried!"
Randy: "I understand that now, Dad. You're taking the company line. You're a sellout. But then to be a sellout, you'd have to have principles to begin with."
Tim: "Hey, I not only have principles, but I'm your ride home!"
Randy: "I'll take public transportation!"
Tim: "Hey, don't use your fancy words with me. It's called a bus!"
[the boys are trying to stop Tim's snoring]
Brad: "What if we hold his nose shut?"
Randy: "Then he'll breath through his mouth."
Brad: "What if we hold his nose and mouth shut?"
Randy: "I think that's called murder."
Randy: [Brad has spelled "Melonology" on a Scrabble board] "Melonology?"
Brad: "The study of melons."
Randy: "There is no such thing as melonology."
Brad: "Oh yeah? Call the produce department at the grocery store, and find out!"
Randy: "Who should I ask for, the melonologist?"
August Rush: "I believe in music the way some people believe in fairy tales. But I hear it came from my mother and father. Once upon a time, they fell in love."
Vanessa Loring: "Your parents are probably wondering where you are."
Juno MacGuff: "Nah... I mean, I'm already pregnant, so what other kind of shenanigans could I get into?"
Juno MacGuff: [showing ultrasound photo] "It's a baby. It's your baby. It kinda looks like it's waving, you know, like it's saying, "Hey Vanessa, will you be my mom?"
Vanessa Loring: "Aww, it kind of does."
