Young Sipho goes into the kitchen where his mother is baking.
He puts his hands in the flour and covers his head with it.
He says: "Look mamma, I am a white boy!"
His mother slaps him hard on the face and says:
"Sipho, go show your dad what you've done!!"
So he does, and his dad slaps him too.
His granny happens to be right next to his dad and she slaps him vehemently in disgust.
Then Sipho's mom says: "Did you learn something from all this?
The poor little Sipho shakes his head, crying and says:
"I did. I've only been a white boy for 5 minutes and I'm already shit scared of you blacks!"
