Good! Now, get the hell out of here, we're closed

[Will and Dennis are approaching Arnie who has just parked Christine in Will's garage] Will Darnell:
[to Dennis]
I knew a guy had a car like that once. Fuckin' bastard killed himself in it. Son of a bitch was so mean, you could've poured boiling water down his throat and he would've pissed ice cubes! [to Arnie] Will Darnell:
Okay. That's the last time you run that mechanical asshole in here without an exhaust hose... I catch you doing it one time, and you're out, you understand? HUH? Arnie Cunningham:
Yes, sir. Will Darnell:
And I'm gonna tell you something else right now. I don't take any shit from you kids. This place is for working stiffs gotta keep their cars running so they can keep bread on the table, it's not for rich-assed, snot-nose kids who wanna go dragging around on the Orange Belt. I don't allow no smoking in here, neither! You wanna' butt, you go out in the junkyard! Arnie Cunningham:
Oh, well I don't sm... Will Darnell:
[interrupting]
Don't interrupt me, punk! Don't interrupt me, don't get smart! Dennis Guilder:
Uhh, sir? Will Darnell:
What? Dennis Guilder:
[points at Darnell's own men who are smoking at a card table]
Those men over there smoking. You better tell then to stop. Will Darnell:
You trying to help your buddy right out of here, jerk? Dennis Guilder:
Nah. Will Darnell:
Then shut your pie-hole. I know a creep when I see one. I think I'm looking at one right now. [turns back to Arnie] Will Darnell:
You're on probation... you get it? You screw around with me once, I don't care how much money you paid up in front, I'll throw you out on your ass! Now you got it? HUH? Arnie Cunningham:
Yessir, yessir. Will Darnell:
Good! Now, get the hell out of here, we're closed
