Not a comedy film, but has it's moments.
  • Radio Raheem gets into an argument with Sonny, the Korean owner of the local grocery store, over the latters lack of English skills.
    Sonny: Motherfuck you!
    Raheem: "Motherfuck me?" [beat] You're alright man.
  • Buggin' Out (who has a ridiculous haircut) is telling the three guys sitting at the corner they should boycott Sal's. One of them responds "You oughta boycott the barber that fucked up your head!"
