Funny / Once Upon a Time in the West

  • While the film is far more serious than the Dollars Trilogy, constant sarcasm from Harmonica and Frank occasionally crosses the line into hilarious.
    Frank: How can you trust a man who wears both a belt and suspenders? The man can't even trust his own pants.
    • Guess where Frank shoots the informer when the idiot proves to be too much of a liability? Hint: Frank shoots him three times...
    • And Cheyenne's reaction to the informer's death is deadpan: "Told you to keep your mouth shut."
    • Also an in-joke. Leone himself wore a belt and suspenders.
  • Some scenes in the 11 minute intro, probably an intentional example. And the tense and cool exchange afterwards.
    Harmonica: Did you bring a horse for me?
    Frank's Man: Looks like we're shy one horse.
    Harmonica: (shakes head) You brought two too many.
  • Hilarious scene:
    Harmonica: I saw three of these dusters a short time ago, they were waiting for a train. Inside the dusters, there were three men.
    Cheyenne: So?
    Harmonica: Inside the men, there were three bullets.
  • This little gem:
    Harmonica: The reward for this man is 5000 dollars, is that right?
    Cheyenne: Judas was satisfied with 4,970 dollars less.
    Harmonica: There were no dollars in them days.
    Cheyenne: But sons-of-bitches? Yeah.
  • Some Black Comedy
    Morton: Tell me, was it necessary that you kill all of them? I only told you to scare them.
    Frank: People scare better when they're dying.
  • Cheyenne doesn't care one iota about the final duel and is just annoyed when the shooting makes him cut himself while shaving.
  • The exchange between Jill and a barman.
    Barman: I can tell you're accustomed to fine living. Bet you come from one of those big Eastern cities.
    Jill: New Orleans.
    Barman: New Orleans!
    Jill: You've been there?
    Barman: No.
  • Frank's henchman Snaky's reactions to a fly landing on his face that he doesn't even bother to swat away with his hand. Finally he traps it in a gun barrel. When it stops buzzing inside, he checks to see if it's dead, only for it to start buzzing again.
  • In the same scene, a residue from the ceiling keeps dripping onto Stony's head, repeatedly. He puts on his hat and the water keeps dripping onto his hat instead.
  • The Native American woman who is chased out of the station mutters to herself as she runs, "Dumb palefaces..."
