The Big Lebowski

The Dude: Walter, ya know, it's Smokey, so his toe slipped over the line a little, big deal. It's just a game, man.
Walter Sobchak: Dude, this is a league game, this determines who enters the next round robin. Am I wrong? Am I wrong?
Smokey: Yeah, but I wasn't over. Gimme the marker Dude, I'm marking it 8.
Walter Sobchak: [pulls out a gun] Smokey, my friend, you are entering a world of pain.
The Dude: Walter...
Walter Sobchak: You mark that frame an 8, and you're entering a world of pain.
Smokey: I'm not...
Walter Sobchak: A world of pain.
Smokey: Dude, he's your partner...
Walter Sobchak: [shouting] Has the whole world gone crazy? Am I the only one around here who gives a shit about the rules? Mark it zero!
The Dude: They're calling the cops, put the piece away.
Walter Sobchak: Mark it zero!
[points gun in Smokey's face]
The Dude: Walter...
Walter Sobchak: [shouting] You think I'm fucking around here? Mark it zero!
Smokey: All right, it's fucking zero. Are you happy, you crazy fuck?
Walter Sobchak: ...It's a league game, Smokey.
