"ALF"
ALF: If you love something, let it go. If it comes back to you, it's yours. If it's run over by a car, you don't want it.
ALF: [ALF almost kills Willie with the TV] Willie, it was an accident!
Willie: An accident? An accident? You almost killed me, and you say it was an accident?
ALF: Alright, let's call it a mistake!
I still think I should have brought her something, you know? Some candy, some flowers...a Rambo doll...
[ALF is trying to be a professional shrink and he's annoying Kate and Willie]
ALF: Speaking of aggravation, we've got to do something about Brian.
Kate: What's wrong with Brian?
ALF: He's been experiencing some negative stroking from Kate lately.
Kate: [in a sudden burst of anger] All right. That's it.
Willie: Calm down.
ALF: Stop ventilating.
Kate: I am not ventilating. I am talking.
[to Willie]
Kate: And I resent the implication that I'm having a negative effect on my son's outlook. Oh I give up. I give up.
ALF: You're letting out your emotions. Good. Now we can make some real progress.
Willie: And you are spouting out a lot of psychological clichés you don't even understand.
ALF: Why so hostile, Willie? I'm okay. You're okay.
Willie: This must stop.
ALF: That's right. A good scream. Let it fly.
Willie: You cannot keep aggravating people like this.
ALF: Why do you hate your mother?
[ALF has just squirted Willie with a squirting flower]
Willie: You amaze me. You're 229 years old and that's what you think is funny.
ALF: Back home on Melmac, I had a cousin, Pretty Boy Shumway. He was so mean, if he didn't like your looks,
[points at Willy, imitating machine gun sound]
ALF: ak-ak-ak-ak-ak.
Willie: You mean he'd shoot you if he didn't like how you looked?
ALF: No. He'd just point at you and go, "Ak-ak-ak-ak-ak."
Jake Ochmonek: Laura's very curious about her secret admirer, so I was thinking like actually saying something to her.
ALF: Danger, Will Robinson.
ALF: Trust me, I'll have her running trough the streets screaming your name. If the cops don't pick her up, she'll be yours.
[Kate refuses ALF to baby-sit Eric]
ALF: But why, why?
Kate: Why? Cause you're irresponsible. You trashed the living room, blew up the kitchen, wallpapered the shower...
ALF: It was a rhetorical question.
ALF: I'm a cursed Melmacian, I belong to the room of the goshdarned.
Kate: Goshdarned?
ALF: Ours was a polite society.
ALF: I hate musicals. Out of the blue people burst into songs.
Willie: Hence the term "musical."
ALF: Yeah, but wouldn't it get on your nerves if all of a sudden I started singing : "Hey, Kate, ain't it great? Hey, Willie, you look silly. Hey!"
Willie: It's getting on my nerves.
ALF: So what musical are you going to go see today?
Willie: "Cats."
ALF: Take me, please! Then afterwards, we can go backstage and eat the actors!
ALF: I'm on a new diet. I can eat as much of whatever I want.
Lynn: And you lose weight that way?
ALF: You do?
