The most memorable no-line, one line, or never seen again person/char. in a movie

Bernie.

Jerry Lewis in The Bellboy.

Cyborgs don’t feel pain. I do. Don’t do that again.
I can’t believe after 3 pages (including another Full Metal Jacket Quote), no one has posted this memorable one-line never seen again character:

Da Nang Hooker AKA “Me so horney! Me love you long time!”

I mean 2 Live Crew did an entire song based on her one line!

Since I just re-watched it last night:

The old guy in the lobby of Elwood’s motel …

“Hey, boy. Did you get my Cheez-Whiz?”

I love how random it is, driven home by Elwood pulling a can of Cheez-Whiz out of his back pocket and flipping it over to him.

He had lots of lines but for not recalling seeing him in any other movies, the best friend in “Big.”

A number of characters similarly from “Josey Wales,” like the funky old lady in the rocking chair (“you can just pay me when you see me again”) or salesmen with the miracle product or the kid who died.

The “real smooth shave” guy in the police station in Highlander.

The “you rebel scum” guy in Return of the Jedi.

The “someone Christ, King of the Jews” guy in Jesus Christ Superstar.

Drew, the “O-face” guy in Office Space. He has a bit part later in the film but it doesn’t amount to much

How is it with stains? ::hoick::

The payoff for that scene is that when you glimpse the salesman later in the movie, the tobacco stain is gone. Not referred to, just gone.

In the extended version, there’s a scene showing Elwood working in the Cheez-Whiz factory, IIRC.

In Back to the Future Part II the guy who accuses Marty: “Did you just take that guy’s wallet? I think he just took that guy’s wallet!” Which he then reiterates a few scenes later. Always makes me laugh.

Are you thinking of this scene from Citizen Kane?

Either that, or City Slickers.

I like City Slickers.

Maybe it’s the hat, maybe the dance, but I have nothing but love for the “Gimme the cash!” robber from Fifth Element.

Some friends who really like Ghostbusters like hearing the grim news from a one line guy in the mayor’s office that “the walls in the 53rd precinct were bleeding.” As in this demotivational poster.

I always felt sorry for the guy in The Empire Strikes Back who warns Solo that his Tauntaun will freeze before he gets to whatever marker. Solo retorts that he’ll see the guy in hell. Which must hurt, however badly the line about the warning was delivered.

I mean, “in hell”? Why? A heads up that when the Empire comes a-calling that guy’s had it and should look forward to more unpleasantries to follow?

I’m not sure if these have been mentioned or not, since I have not been able to see page 2 for some reason. I am sure it is my iPad acting up again, but I’ll throw a few more into the mix

Steve Buscemi in Pulp Fiction. He was the waiter Buddy Holly in Jack Rabbit Slims.

Jerry Lewis in It’s a Mad, mad, mad, mad world. As the car driver who swerves to purposely hit the captains hat. That is the single best scene of Jerry Lewis’ career.

I’m sure it’s been mentioned, but I’ll do it here in case it hasn’t. Lucille, from Cool Hand Luke.

From above, Josey Wales has some great character actors in it. One that appears early in the film, when the kid is laying on the ground shot and talks about the gold. The guy that has the rifle on them is Uncle Leo from Seinfeld fame.

I had another, but it slipped my mind.

Same movie: “I’ll take the next one.”

Captain Koons (The guy who gave Butch the watch.)

Just saw this on Hulu for the first time in a while - that was Mathieu Kassovitz, who I recognized as the love interest in Amelie and more recently one of the bad guys in Haywire.

Paul Reuben’s as Pee-Wee playing Pee-Wee in /Pee-wee’s Big Adventure/: “Paging Mr. Herman!”

The actress in the porn moviehouse in Taxi Driver, what with Travis getting the Jujubees. “do you want me t call the manager? Troy!”

Crazy Lee from /wild bunch/, maybe a bit long to count. “kiss my sister’s black cat’s ass.”. Seems like one scene to me.

The radiator dancing girl from /Eraserhead/ really just only does the one thing. Dance. Or whatever she’s doing.

Did you read the OP? Because I don’t remember Captain Koons only have one or zero lines. In fact, I specifically remember him having a whole monologue.
