NASA was interviewing professionals to be sent to Mars. Only one could go, and he will not return to Earth. The first applicant, an American engineer, was asked how much he wanted to be paid for going.
The next applicant, a Russian doctor, was asked the same question. He asked for two million dollars.
'I wish to give a million to my family,' he explained, 'and leave the other million for advancement of medical research.'
The last applicant was an Indian politician. When asked how much money he wanted, he whispered in the interviewer's ear, 'Three million dollars.'
