The first movie on that list is hands-down, without a doubt...(drumroll)
I *love* that movie! Always have, always will. I mean, how can you NOT love that movie with lines such as:
"What's happenin', hot stuff?"
"Last night at the dance, my little brother paid a buck to see your underwear."
"Ted, that's a Rolls Royce! Ted, that's the prom queen!"
"Who's he?" "That's me." "Well who are you?" "I'm him." "Oh. Okay."
Here are others, in no particular order:
O Brother, Where Art Thou? "Hop in, boys! I'm gonna R-U-N-N-O-F-T!"
Weird Science "How 'bout a nice, greasy pork sandwich served in a dirty ash tray?"
Titanic (Natch.) "I'll never let go, Jack!"
Ever After "There was a bee, Your Majesty."
Kingpin "...and how you got Miss Claudia to stop be so much of the whore that she is."
Coal Miner's Daughter "Stop a'growlin' at me, ya sound like an ol' berr."
Elizabeth "No, he shall live, so that I will always remember how close I came to danger."
Election "Good morning, Mr. McAlister. You look like you could use a cupcake."
The Breakfast Club "Could you describe the ruckus, sir?"
Fargo "Dee-ad! Are ya stayin' fer supperrrr?"
The Shawshank Redemption "Time to get busy livin' or get busy dyin'."
Shakespeare in Love "Have a care with my name. You will wear it out."
Aaaaand, my guilty pleasure is...
ATL. "Teddy ain't never been outside 285 in his life, and he proud of it."
