(So, before this scene we can see that one of the main characters, Bolec, is a big fan of a black US culture: music, movies etc and he thinks that Polish people are "lacking of chill" and they should learn it from a black people)

• Wait, what is your name again? (wordplay)

Fred: Remind me whats your name? Kolec? Stolec? (Spike? Feces? - wordplay)

Bolec : Bolec (~Bolt)

Fred: So listen carefully now, Bolek (nick->name,not his). Did you ever go to America?

Bolec: No.

Fred: Exactly and i .. i know someone who was and told me few things. Do you know how they brought blacks to America?

Bolec: From Africa..

Fred: Exactly, slave traders brought them back from Africa, but do you think its such an easy job to get out on the beach, catch in a net a strong, big black man and bring him back over the ocean?

Bolec: I dont think so.

Fred: Obviously not, they did it because they only cought those that either could not ran off from the net or were the most stupid members of the clan/tribe and so the chief sold them off for a pack of cigs because he would not have anything useful coming out of them, and all those losers were brought to America, got married, had children the world moved on, we started to have computers, amphetamin, airplanes but what of it?! if their hearts pump the same blood, they are the descendants of a man who allowed for himself to be cought on his own soil in a net, so i dont think our boys (Polish mafia) lack anything good, UNDERSTOOD !?

Bolec: Nods

Fred: Gruha, open the case.

For all black people reading it - sorry. It is quite old film by the way,no chance they would ever make such dialogue in present times. If you feel "offended" sorry
