Japanese doctor says, 'Medicine in my country is so advanced that we
can take a kidney out of one man, put it into another, and have him
out looking for work in six weeks.'
A German doctor says, 'That is nothing. We can take a lung out of
one person, put it into another, and have him out looking for work in
four weeks.'
A British 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 both of them out looking for work in two weeks.'
The American doctor, not to be outdone, interjected, 'You guys are
way behind. We are about to take a woman with no brains, and no
heart, put her in the White House, and very soon half the country
will be out looking for work.'
