Which country is the most advanced????

A British doctor says, "Medicine in my country is so advanced that we can take a kidney out of one man, put it in another and have him look for work in six weeks."A German doctor says, "That's nothing, we can take a lung out of one person, put it in another and
have him look for work in four weeks."A Russian doctor says, "In my country medicine is so advanced that we can take half a heart out of one person, put it in another and have them both look for work in two weeks."The American doctor, not to be outdone says,"You guys are way behind. We just took a man with no brain out of Texas, put him in the WhiteHouse, and now half the country is looking for work, and the other half is preparing for war."
