Two stumblebum inheritors are determined to rid their antique house of a mouse who is equally determined to stay where he is.

Lars: I don't believe it. He snapped the trap, ate the olive and left the pit just to mock us!
Ernie: I think you're giving him a little too much credit. Mice don't mock. They don't have a sense of humor or irony. He's not sitting in his hole in a smoking jacket sipping cognac, and giggling to himself, "I left the pit!" The trap snapped itself, the olive flew off and he ate it. It's just that simple. But now that he knows we're here, he won't come within a mile of us. I don't think we'll be seeing any more of that...
[sees mouse in cereal bowl]
Ernie: MOUSE!
Ernie: No capers? But that's just grilled cheese. What's the point? Why don't they eat out of a trough!
[addressing the clients of the diner]
Ernie: Which one of you palateless sheep sent my sandwich back?
Ernie: [making speech and as he does, the mouse is within the podium. Ernie tries to crush it with the gavel, and yells out words as he hits the gavel] When Quincy Thorpe of the Historical society told us the value of this house, you, uh, could have KNOCKED us over with a feather! We, uh, we didn't know what HIT US! The house was in terrible disrepair, but it wa snothing that a few NAILS... and some old fashioned elbow grease couldn't fix.
Ernie: [to Lars] Come on. You loved string!
Lars: I didn't love string!
Ernie: Well, you could have fooled me! You and Pop were always huddled together running some piece of something through your fingers. It didn't matter what I did. I didn't even exist! I made him my special rack of lamb for his 70th birthday.
Lars: [sighing in resignation] Oh, no!
Ernie: Yes! You remember. I slaved over that meal, making sure everything was perfect. Did he say, "Thanks, Ernie, it was delicious"? No. He only noticed the string I had tied it with.
[Ernie takes a shotgun off the wall]
Lars: What are you gonna do?
Ernie: I'm gonna kill that unspeakable thing once and for all.
Lars: Ernie, no, no...
Ernie: Stay back, Lars! I'm a man on a mission!
Lars: This is how accidents happen, come on, Ernie, just put the gun down...
Ernie: I'm gonna blow his furry little head off, and I'm gonna splatter his devious little mouse brain from here to kingdom come!
[first lines]
Lars: [at their father's funeral, they carry his coffin down the steps of a cathedral] Hold your end up higher, you're not holding it.
Ernie: I am too.
Lars: You are not.
Ernie: Don't worry about me. Hey, isn't that suit charcoal?
Lars: No.
Ernie: Looks charcoal gray to me, some gray polyester blend. Couldn't even find a black suit for your own father's funeral.
Lars: It's black.
Ernie: No, I'm sure it's gray.
Lars: It's black.
Ernie: Gray.
Lars: Black.
Ernie: Gray.
Lars: Black!
Ernie: Fine, it's black. It's the grayest black I've ever seen.
Lars: It doesn't matter what color it is!
[the handle on the coffin breaks off and the coffin slides down the steps]
Lars: I'm sorry, Pop! I'm sorry!
[the mouse is lying helpless in front of the two Smuntzes]
Lars: Look, he's still breathing.
Ernie: Well, kill him! Find a blunt object!
[Lars grabs a fireplace shovel and raises it over the mouse]
Ernie: Let him have it!
[Lars tries several times, but can't]
Ernie: What the hell are you waiting for?
Lars: I can't just hit him with a shovel.
Ernie: Why not?
Lars: Well, look at him, he's pathetic!
Ernie: Pathetic? He's Hitler with a tail! This is The Omen with whiskers! Nostradamus didn't see this thing coming!
Lars: Ernie, he's a living thing...
Ernie: Not for long, give me that!
[He grabs the shovel and tries to whack the mouse, but can't]
Ernie: I CAN'T!
[He sobs, beating his own forehead with the shovel]
Ernie: Look at him just lying there. It just doesn't feel very sportsmanlike!
Lars: We'd better do something quick, I think he's coming to!
[Cut to Lars and Ernie driving to the Post Office. Ernie is holding a small box addressed "TO FIDEL CASTRO, HAVANA, CUBA." Scratching is heard inside the box, and Ernie raises it to his ear]
Ernie: Aw... I forgot to put holes in the box.
[Ernie chuckles evilly. At the Post Office, they drop the box through a slot and watch it slide down the mail chute]
Ernie: Hasta la vista, you little rat bastard!
Lars: Wow, did you feel that?
Ernie: What?
Lars: I got a chill. You should never talk about Pop like that.
Ernie: Really? What's this do for you?
[shouting]
Ernie: Thanks for nothing, you string-sucking old loon!
Lars: He didn't mean it, Pop.
Ernie: [speaking in a fake French accent while serving the Mayor and his wife] Duck a l'Orange avec du quack sauce. And for ze Mayor, la specialty de la maison, Lobster Loaf a la Ernst ou la bibliotheque.
Lars: Well, these are all kittens. We were hoping for an older cat, one with experience.
Maury, the Cat Care Society Owner: That's a switch. Most people like the cute little ones. Experience with what?
Ernie: Mouse-hunting.
Maury, the Cat Care Society Owner: Oh, all cats are good mousers.
Ernie: Yes, but you see, we have huge rats, the size of sumo wrestlers, and lots of 'em, so we really need a ferocious feline, preferably one with a history of mental illness. I'm talkin' one mean pussy.
Lars: Yeah! A vicious cat, difficult to love. You got any of those knocking around your cages?
Maury, the Cat Care Society Owner: Funny you should ask. I had given up hope of anyone wanting him. We were about to gas him again.
Lars, Ernie: "Again"?
Ernie: I don't think we're dealing with an ordinary mouse.
Ernie: He's Hitler with a tail. He's "The Omen" with whiskers. Even Nostradamus didn't see him coming!
[the Smuntzes have covered the entire kitchen floor with mousetraps]
Lars: Don't you think this is a little much?
Ernie: Never underestimate your opponent. Let's say he has mastered a way to empty a mousetrap without getting caught. If he snaps one of these babies, a chain reaction will start snapping them all. He'll panic, and the law of averages says one of them has to nab him.
Lars: Not bad.
Ernie: Yes, well, I like to use both sides of my brain. Come on, let's hit the sack.
[they get up to leave, only to realize they locked the door and that they are all trapped in with a bunch of loaded mousetraps]
Ernie: [bowing to the Sheik at the auction] Hakuna Matata.
Lars: Some things are more important than money, Ernie.
Ernie: Notice it's always the financially challenged who say that?
Caesar: I've activated the Squeak Seeker 2000.
Ernie: Hey! Don't go!
[indicationg the flood in the house]
Ernie: A demonstration of how durable a LaRue really is! Now you know this house will last *forever*!
[the house crashes down]
Alexander: I own eveything of LaRue. His books, his letters.
[signifies shoes]
Alexander: You see these shoes?
Ernie, Lars: LaRue's?
Alexander: No, but I'm sure he would have loved them.
Ernie: [reading the tag on the side of the cage] "Catzilla"?
Maury, the Cat Care Society Owner: Oh, you know the guys who clean up call him that. But you can call him anything you want. I'd say he looks more like a "Fluffy."
Lars: [leans down] Aw, poor little Catzilla. You want a home, don't you? You want to get out of here. Well, you're gonna have to kill, kill, kill for it!
Ernie: You're a stupid cat, aren't you? Yes, you are! And you're ugly, too...
[the cat lunges, Maury subdues him with a taser]
Lars: [noticing his torn coat sleeve] Oh, you little bastard!
Ernie: We'll take him!
Lars: [Ernie's in the hospital after being hit by a bus] Ernie, are you okay? I came as soon as I heard.
Ernie: Why are you wearing a pink overcoat?
Lars: Because April gave us the 1200 dollars!
Lars: Look! You blew a hole in the floor!
Ernie: And I distinctly remember somebody yelling, "Shoot! Shoot!"
Lars: Yeah, well you never listened to me before!
Ernie: [after releasing the cat into the house] Well... I almost feel sorry for the little fella.
[pause]
Ernie, Lars: Almost!
[laugh]
Cuban Post Office Guy: [the post office in Cuba has just received the mouse] Damn Americans, always trying to cheat us!
Lars: You think I didn't have other things I wanted to do with my life? You think I didn't have ambitions of my own?
Ernie: Ambitions?
[laughs]
Ernie: Come on, you love string!
Ernie: [to a female passerby] Hey, merry Christmas.
[she ignores him and keeps walking]
Ernie: Yeah, I was on top once, too. But there's only one way to go from there, and that's down, baby, down!
Ernie: Shh! He's goin' for the cherries!
Lars: I thought you said mice like Gouda.
Ernie: Not in the morning! Cheese tires them out. They need fruit for energy.
Ernie: [mailing the mouse to Cuba] Hasta la vista, you little rat bastard!
Alexander: [talking to Ernie] You know, it would be a shame if you boys put on this auction and nobody bid.
[the Smuntzes get covered in sewage in trying to suck up the mouse with a vacuum, only to get it attached to the sewage line. Meanwhile, they also receive a notice from the bank about the house being foreclosed]
Ernie: [seeing the notice] What's this?
The Banker: We're foreclosing on your house. You quit paying your mortgage.
Ernie: Oh, wait a minute, I think there's been some mistake. This house is paid for.
The Banker: No, it *was* paid for, but you borrowed against it. If you don't pay the $1,200 overdue, we repossess it.
Lars: [in disbelief] Twelve hundred dollars?
Ernie: How long do we have?
The Banker: One week from, uh, five days ago.
Ernie: [shocked] That's two days! Look, we don't have the time or the energy to deal with these petty problems now. We're in the midst of an extensive renovation.
The Banker: [noticing that they're covered in sewage] Looks like you're off to a great start.
Ernie: Just think of all the trouble we could have saved ourselves if we just threw fruit at him in the first place!
Ingrid: Hilde, the spool is smoking!
April Smuntz: Does a wife need a reason to visit?
[takes champagne glass from passing waiter]
April Smuntz: I didn't know you were entertaining.
Ernie: Don't you mean *ex*wife?
April Smuntz: That remains to be seen.
Ernie: [Caesar is being carried out on a stretcher] Caeser! Are you all right? Try to think, did you catch that mouse?
Caesar: What's that? Horse? *Fiendish*! I won't eat it!
[he has lost his mind]
Caesar: Aaaagh!
[he begins chattering like a mouse]
Crying Child: [screams] No, no, no, Fluffy! No! No, I want my kitty! No! No! No! No! No! Fluffy!
Caesar: You have to get inside their mind. You have to know what they want, need. You have to think... like a mouse!
Lawyer: [about their new house] It's interesting. it seems the previous owner was found locked in a trunk in the attic...
Lars: We made love in a way I've-I've only ever seen in nature films!
Ernie: I like to use both sides of my brain
Ernie: I hate you!
Lars: And I hate you!
Ernie: Not as much as I hate you!
Lars: Yeah!
Ernie: Yeah, DOUBLE! DOUBLE! Oh, give me something!
[Starts looking for something to throw. Lars grabs an orange]
Ernie: I'm gonna brain you!
Lars: 'Ere it is!
Ernie: Oh, yeah! Give it to me then! Go ahead!
[Lars throws the orange. Ernie ducks and the orange hits the mouse, who was watching. Ernie spots the mouse]
Ernie: [Almost relieved] You killed him!
Ernie: [Ernie is being bombarded by angry factory workers] Light a match; they're frightened by fire!
Caesar: You got asbestos all right.
[points to floor]
Caesar: I'll bet it's up in the ceiling mostly. Should take me only a day, or two, to remove it.
[Quoting his father]
Lars: A world without string is chaos.
Lars: Ah, you must be Caesar.
Ernie: Hello, Mr. Caesar. Glad you could come so quickly.
Caesar: Shh.
[has a quick look-around]
Caesar: You have mice.
Lars: [under his breath] He's good.
Lars: [as his wife is packing a suitcase] Please, April, don't go.
April Smuntz: I'm not going anywhere.
[frame cuts to Lars standing on the porch with the suitcase]
Lars Smuntz: [they are trying to vacuum up the mouse, they instead are vacuuming up sewage] Damn, that mouse stinks!
Ernest Smuntz: Dead animals always do.
Lars Smuntz, Ernest Smuntz: [they start laughing maniacally]
Lars: You used to love string.
April Smuntz: That was before, when I was dating the son of wealthy string magnate! Not now when I am married to the half owner of a worthless deathtrap!
The Mayor's Wife: [after the mayor swallows a cockroach and passes out] Oh, no, not again!
Ernie: I'm gonna build an Olympic-sized swimming pool and fill it with pina coladas and a college sorority.
Alexander: There's a lot of Eurotrash out there scarfin' up the shrimps.
