So this white kid was playing in his parents bedroom right..

He takes some black shoe polish out of his dad's drawer and smears it all over his face.
His mom came in the bedroom and he decided to make a joke of it. "Look Mom, I'm black!" he said.
His mom slapped him across the cheek. "I can't believe you just said that boy, go tell your father what you just said."

Surprised and a little hurt, he walked over to his Dad in the TV room and said "Hey look Dad... I'm black!"
When his Dad heard that, he flat out punched the kid. Square in the face. The kid was shocked and confused. The Dad said "Boy that's the worst shit I've ever heard, go and show your grandma what you did and tell her what you said.

So the kid begrudgingly walked upstairs and walked into his Grandma's bedroom. "Hey Grandma look, I'm black..."
...and his Grandma just pummeled him. Relentlessly. So hard that both the kids' parents had came upstairs to break up the beating.

They all stood around him and asked him "Yeah well how do you feel about making that joke now?"
The kid just looked up at them and said "...Well I've only been black for 10 minutes, and I hate all you crackers already!"
