Three doctors are arguing: an Israeli, a German and a Briton.
The Israeli says, 'Medicine in my country is so advanced we can take a kidney out of one chap, put it in another, and have him looking for work in 6 weeks.'
The German says, 'That's nothing. We can take a lung from one punter, put it in another, and have him looking for work in only four.'
The Brit says, 'Give over! We can take an arse from Scotland, put him in Number 10, and have half the country looking for work within 24 hours!'
