(long time since I saw the movie) From what I'm reading here, the audience and characters don't know and aren't expected to know that. The name is hard for them because it is foreign to them. To turn the name into a joke that they are 'never gonna work here anyway' explicitly links the racist prejudice against them to their name. The name was probably especially ridiculous because they wanted to make the pun above, but the point is the racism surely, not the everyday humour in linking a foreign person's name to their non-employment?
