Classic Lines from Crash

Elizabeth: My fathers from Puerto Rico. My mother's from El Salvador. Neither one of those is Mexico.
Graham: Ah then I guess the big mystery is who gathered all those remarkably different cultures together and taught them to park their cars on their lawns?

Country song:
Gonna buy me a rope and lynch me a nigger
I'd shoot 'em dead first but I done broke my trigger
Gonna get out my sheet Put my hood on my head
Gonna string 'em up good
Then they'll be dead
Home of the brave and the land of the free
