An Israeli doctor

An Israeli doctor says “Medicine in my country is so advanced that we can take
a kidney out of one man, put it in another, and have him looking for work in 6
weeks.”
A German doctor says “That is nothing; we can take a lung out of one
person, put it in another, and have him looking for work in 4 weeks.
A Russian 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 them both looking
for work in 2 weeks.”
The Texas doctor, not to be outdone, says “You guys are way behind, we
recently took a man with no brain out of Texas, put him in the White House for
four years, and now half the country is looking for work.”
