I thought that was fucking great, here is why:
I conveys a valid point.  Think about it, what if that bus would have been full of Black guys or Mexicans?  You would have though "Ya I could see that shit happening some day."  The way things are going in this country, the hate an intolerance.  But because its a made up race, Gingers, it is actually kind of funny at first.  South Park pointed out how stupid humanity is and our constant quest to create cultural and ethnic devides between us by making up "Ginger Kids".  I am not sure if they were first but that was the first place I heard it.
I remember in like 5th grade the teacher did an experiment, she said that everyone in the class who had blue eyes could go out to recess, kids with other colored eyes had to stay and clean the class room.  Once back from recess the blue eyed kids were allowed to sit whever they wanted, then the teacher said that a new study came out that said blue eyed children were smarter and better at learning and they would be getting special treatement the rest of the school year.  Of course as expected the blue eyed children all hung out the rest of the day while the other kids stayed together and started hating them.  That experiment, like this video shows how arbitray our racial hatred is.
Black, ginger, mexican whatever, there are no real divedes between us, only what we create ourselves.
I also liked it because it was fucking crazy and Lady Gaga was not in it.
