It's kinda like having a car that is really a pile of junk, but you paint it up to look really nice and expect a good ride.
I just watched the Southpark episode where the teacher got a sex change operation and then was furious to find out he couldn't get pregnant. Then Kyle's father gets a dolphinoplasty to become a dolphin. Then Kyle gets a negroplasty to become a tall black kid so he can make the basketball team (the coach has previously told him jews can't play basketball.) They find out that the dolphin dad can't swim, and the kid can't play basketball without his knees exploding. It's all appearances. It doesn't change the reality.
