If you haven't seen "Be Cool" the set up for this scene is that the Russian Mobster just call Sin LaSalle who is played by Cedric the Entertainer the n word and to be cool.
"Have you lost your mind? I mean, how is it that you can disrespect a mans ethnicity when you know we've influenced nearly every facet of white America... from our music to our style of dress. Not to mention your basic imitation of our sense of cool; walk, talk, dress, mannerisms... we enrich your very existence, all the while contributing to the gross national product through our achievements in corporate America. It's these conceits that comfort me when I am faced with the ignorant, cowardly, bitter and bigoted, who *have* no talent, no guts? people like you who desecrate things they don't understand when the truth is - you should say thank-you, man? and go on about your way. But apparently you are incapable of doing that! So...
[shoots his gun ] "
"... and don't tell me to be cool. I *am* cool! " (and kills the mobster)
By far my favorite quote.
