Tremors/Funny

In the first film, Melvin pretending a severed snake-tongue is strangling him.
Later, Melvin scaring Earl with a basketball.
"I feel I was denied critical, NEED TO KNOW, information!"
- "I am completely out of ammo." baffled pause "That's never happened to me before.."
"We killed it... we killed it! FUUUCCCKKKK YOOUUUU!!!! FUCK YOU!"
Really, the banter between Earl and Val just makes the entire first movie:

"I ask you, is this a job for an intelligent man?"
"I dunno. Show me one and I'll ask him."

"See you later Chang, we've got a schedule to keep."
"Yeah, we plan ahead, that way we don't do anything right now. Earl explained it to me!"

"Dammit, Val, listen to me, I'm older and I'm wiser!
"Yeah well, you're half right."

"Hey, Rhonda, you ever hear about anything like this before?"
"Oh, sure, Earl, everybody knows about 'em, we just didn't tell you!"

"No way they can outrun the horses."
"Shit for all you know they can fly."

"Well I'm a victim of circumstance."
"Thought you called it your pecker."

BROKE INTO THE WRONG GODDAMN REC ROOM, DIDN'T YOU, YOU BASTARD!!
"Hey, Melvin, wanna make a buck?"
In the third film, Burt, under the assumption that eating makes Ass-blasters reproduce like Shriekers, blow up his compound to keep one from getting into the food supply. Just as the explosion dies down, he finds out that eating makes Ass-blasters comatose. His reaction is what sells it.

Burt: What sort of supreme being could condone such irony?

The final scene in the third film when Burt leaves Melvin on a short rock. Melvin Cursing him even through the credits makes it even funnier.
- For further context, many fans didn't like Melvin surviving the first movie, wishing that something bad happened to him after all the inappropriate pranks he pulled when danger was on the line. It took two movies, but Melvin finally got what was coming to him. In the third movie, Melvin seemed to turn his life around and managed to even found his own real estate company. However he has his sights on tearing down perfection and building over it. Even at many points trying to get Burt to sell his house. When the Graboids came in initially Burt was all to kill happy for them. However thanks to Nancy calling in outside assistance, which backfires as rather than helping them destroy the Graboids, they instead list them as an endangered species and declares Perfection Eminent Domain. Burt is ticked at first, but in the end of the movie, he uses the law to his advantage by letting El Blanco (The Great White Graboid.) live after the latter saves his life from the last Ass-Blaster. He is later seen sitting on a rock, playing with El Blanco. Using a remote control car fitted with ultrasonic watches so El could follow it. Melvin comes in for one last time to make his offer, but Burt tells him he may want to sit on the rock with him. Before Melvin could question why El Blanco shows up and makes his presence known, scaring Melvin onto the rock. When this exchange happens.

Melvin: Jesus Christ, Burt! I thought you killed all those things.
Burt: I never said that.
Melvin: God, man, kill it! Blow it up! What are you waiting for, Burt?
Burt: The things is, as long as one of these reptilians is still alive, this whole area is deemed protected; you know, pursuant to section 1472-B of the Endangered Species Act. In other words, no houses, no condos, and no ranchettes.
Melvin: You're crazy okay!! These things man, they're gonna eat you Burt!! They're gonna get all of you!!
Burt: We got new Geophones, Graboid Barriers, blanket protection. The whole town agrees. Between you and El Blanco, they'll take him every time. Adios Melvin!!
Melvin: BURT!!! HEY!!! BURT!!! BURT!! YOU ASSHOLE!! YOU DUMB SON OF A BITCH!!! GOD I HATE YOU!! I HATE YOUR GUNS!! YOU SORRY SICK PARANOID RIGHT WING REDNECK PSYCHO!!! SHIT KICKER!!! GODDAMN YOU BURT!!! AND I HATE THAT HAT!!

In the fourth film, when confronted by the Graboids Hiram pulls out his chosen weapon...a tiny .22 pea-shooter.

Hiram: Well you told me to find something I was comfortable with!
Black Hand Kelly: (in disbelief) It's true. I did say that.
