You’re gonna need a bigger boat -Jaws
Phil: Morons. Your bus is leaving.
Mr. Blonde: Are you gonna bark all day, little doggy, or are you gonna bite?
Holden: I’m not saying that I don’t think that a Bluntman and Chronic film isn’t the worst idea since Greedo shot first.
Do’h ! you are of course right 
I guess its time for me to watch the movie again. Guess what’s on my schedule this weekend ? 
“Game over, man! Game over!”
“Why don’t you put her in charge!”
- Aliens
“I’m your huckleberry.” - Tombstone
Everything from the first 45 minutes of Full Metal Jacket
“Of course I’m respectable. I’m old. Politicians, ugly buildings, and whores all get respectable if they last long enough.” Noah Cross (John Huston) in Chinatown.
Just about every single line here.
BTW, great choice in the OP, grisham. When it comes to crude comedies, I don’t think I’ve ever heard a line that made me laugh more. 
That is one of my top 10 movies and I’ve seen it dozens of times but I can’t remember the scene. Refresh my memory?
In Fandango when Judd Nelson, laying on the ground with a failed rip cord clenched in his fist and sure he just augered into the earth looks up at the laundry descending all around him that was accidentally substituted for his parachute and says* “Aaaangels!”*
I am serious. And don’t call me Shirley. – Airplane
“I thought I was dead for a while too…but it turned out I was just in Nebraska.”–Little Bill from Unforgiven after the “Duke of Death” said he thought Little Bill was dead. Particularly funny since I first saw the movie with a girl from Nebraska.
In Blake Edwards’ S.O.B, Julie Andrews refers to Robert Preston as a shyster.
Deeply offended, he replies, “Madam! A * shyster* is a crooked lawyer! I am a quack!
From the movie Snatch:
Turkish (making tea): Would you like sugar?
Brick Top: No thanks, Turkish. I’m sweet enough.
It is bizarre and hilarious in context of this character’s behavior through the rest of the film.
Brick Top: Do you know what “nemesis” means? A righteous infliction of retribution manifested by an appropriate agent. Personified in this case by an 'orrible cunt… me.
In They Live Rowdy Roddy Piper’s character is being chased by the police. He is wearing a pair of special sunglasses that allows him to see the aliens that are infiltrating the Earth for what they really are, even though they’re disguised as humans.
He runs into a bank, carrying a shotgun and wearing a pistol. He stops, panting, in the lobby. He’s disheveled, out of breath, and tired. He looks around, and sees many aliens scattered throughout the bank, disguised as both customers and bank personnel. Everyone has stopped and is staring at this madman who just burst in off the street.
He gathers himself, brings the shotgun to bear, and says:
“I have come here to chew bubble gum and kick some ass.” Brief pause. “And I’m all out of bubble gum.”
And then he starts shooting.
Classic line. Classic scene.
Top Gun: Tom Cruise’s character’s commanding officer, after informing Cruise that he is being sent to the Top Gun flight school:
“And if you screw this one up, I’ll have you flying a cargo plane full of rubber dog shit out of Hong Kong!”
It was earlier in the movie in the Cafe I believe. He says it to the guys he later goes driving with while they are drunk.
From Buckaroo Banzai:
Penny: Buckaroo, you forgot your thruster.
BB: Why don’t you just hold onto it for a while.
Or any of a hundred others from that movie.
“Listen up you primitive zipper-heads…”
“This is my BOOM stick!”
“Gimme some sugar baby.”
Ash, Evil Dead III
