The whole scene in the train station, as George and Grover are trying to elude the cops and make it on board the Silver Streak:
George (As Grover is applying the shoe polish to his face): It'll never work. Never.
Grover: What are you, 'fraid it won't come off?
George (Slaps Grover's hand, giving him "five"): Shit! That's mah man! That's mah main man! (In normal voice) I don't think we'll make it past the cops.
Grover: We'll make it past the cops. I just hope we don't see no Muslims.
- As they board the Silver Streak,
Grover (To the agent with George's picture): Who you lookin' for?
Agent: White guy.
Grover: Well, if I see any, I'll let you know.
