NASA was interviewing professionals to three people were sent to Mars. Only one person will go there and could not return to earth again.
The interviewer asked the first applicant, an engineer, how much he would be paid. "One million dollars," replied the engineer. "I want to donate it all to my alma mater."
The next applicant was a doctor. When asked, he replied, "Two million dollars, I want to give one million dollars to the family and one million dollars for the development of medical research."
Last applicant is a lawyer. When asked how much he would be paid, he whispered to the interviewer, "Three million dollars."
"Why is so much more than others?" asked the interviewer.
The lawyer replied, "You give me three million, I'll give you one million, I myself will take one million, and we send the engineer to Mars."
