A British doctor says: "In Britain, medicine is so advanced that we cut off a man's liver, put it in another man, and in 6 weeks, he is looking for a job."
The German doctor replies: "That's nothing, in Germany we took part of a brain, put it in another man, and in 4 weeks he is looking for a job."
The Russian doctor replies: "Gentlemen, we took half a heart from a man, put it in another's chest, and in 2 weeks he is looking for a job."
The American doctor laughs: "You are all behind us. A few years ago, we took a man with no brain, no heart, and no liver and made him President.
