A white guy walks into the plastic surgeon's office and asks: "I want to be black, can you do that?" "Yeah, but we'll have to add 2 inches to your penis, take away 30% of your brain and make you 70% darker."
"Okay."
After the operation, the surgeon says "I'm sorry, but we've made some mistakes. We cut off 2 inches of your penis, took away 70% of your brain and made you 30% darker, is this okay with you?"
"Si, senor."
