Four doctors meeting at an international conference, each boasting that his country has made the most significant advances in medicine: The Israeli doctor says 'Medicine in my country is so advanced, we can take a kidney out of one person, put it in another, and have him looking for work in six weeks.' The German doctor says, 'That's nothing! In Germany , we can take a lung out of one person, put it in another, and have him looking for work in four weeks.' The Russian doctor says,' In my country medicine is so advanced, we can take half a heart from one person, put it in another, and have them both looking for work in two weeks.' The English doctor, not to be outdone, says 'Aha! We can take an arsehole out of Scotland , put him in 10 Downing Street and have half the country looking for work within twenty-four hours.'
