Looking For Work Joke

My friend "Kee" sent me this joke:

A Japanese doctor said, 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 six weeks. "

A German doctor said, "That's nothing, we can take a lung out of one
person , put it in another, and have him looking for work in four weeks."

A British doctor said, "In my country, medicine is so advanced that we can
take half of a heart out of one person, put it in another, and have them
both looking for work in two weeks."

A Texas doctor, not to be outdone said,
"You guys are way behind. We took a man with no brains out of Texas, put
him in the White House and now half the country is looking for work."
