A young Mexican boy walks up to his mother

...with his face covered in flour and says, "Look mami, I'm a white boy!" His mother takes one look at him and slaps him across the face. She replies, "Go show your father what you have done!"

So the little boy runs to the other room where his father is and shouts, "Papi look! I'm a white boy!" Just as the mother did, the father slaps him across the face and says, "Go show your grandmother what you have done, maybe she can knock some sense into you."

The little boy runs out to the garden where his grandmother is and says, "Grandma, look! I'm a white boy!" His grandmother slaps him across the face, grabs him by the ear and sits him on the floor. She gives him a long speech about why he should be proud to be Mexican and why he shouldn't try to ever cover up his true identity.

The boy then slowly walks back into the kitchen, past his mother. She asks him, "So, what did you learn?" The boy replies, "I've only been white for 10 minutes and I already hate you people."
