In an attempt to assimilate our one black pupil into the local population, we were all invited to his birthday party. Just before this event, our headmaster held a special assembly to explain why some people were black and some were white.
Everybody was born originally black, but because this was a dirty colour, God made a big lake and everybody had to have a wash in it. So, everybody came and bathed and washed off their blackness and became white.
But, the lake was drying up and so there was only enough water for some to wash their hands and feet.
A great story, for many reasons - its mindbending racism, for one. Also the implication that God just didn't bother refilling the lake, and thought "fuck it, let 'em stay black".

How odd. In hot countries, most people bathe at least once a day. In fact, in my grandparents' era in India, people avoided the whites because the pikey soap-dodgers hardly ever washed.

Luckily, we now live in a time of racial tolerance and these outdated stereotypes are forgotten. See the jolly black woman bathing in the Radox advert! She is what she is.
