A black kid is baking a cake with his grandma. She asks him to pass her the flour and he accidentally spills it all over himself. Covered from head to toe, the kid starts laughing hysterically and says "hey grandma, look at me, look at me; I'm a white guy." The grandma slaps him and says, "go show your father what you just did."
The kid, now a bit confused and apprehensive but still finding his situation funny goes up to his father and says; "hey dad, look at me, look at me, I'm a white guy." The father gets upset and smacks the kids and tells him to go show his mother what he just did.
Now the kid is totally confused and very apprehensive. He cautiously walks up to his mother and wearily says; "mom, look at me, i'm a white guy." The mom follows suit and smacks the kid and tells him to go clean himself up and the mess.
The kid walks into the kitchen and the grandma asks; "well, what did you learn?" The kid looks up at his grandma with a stern face and says...
" I've learned that i have only been white for 5 minutes and already distrust you people."
