An Israeli doctor says: "In Israel, medicine is so advanced that we cut off a man's testicles, put them on another man, and in 6 weeks, he is looking for work.
The German doctor says: "That's nothing, in Germany we take part of a brain, put it in another man, and in 4 weeks he is looking for work."
The Russian doctor says: "Gentlemen, we take half a heart from a man, put it in another's chest, and in 2 weeks he is looking for work."

The American doctor laughs: "You all are behind us. Six years ago, we took a Muslim with no brains, no heart and no balls and made him President.   Now, the whole country is looking for work!"
