Return to Earth

A ASA joke for you:

NASA was interviewing professionals to be sent to Mars.Only one could go, but with one catch - he couldn't return to Earth.The first applicant, an engineer, was asked how much he wanted to be paid for going. "One million dollars," he answered, "because I want to donate it to M.I.T."The next applicant, a doctor,was asked the same question. He asked for two million. "I want to give a million to my family," he explained, "and leave the other million to my church."The last applicant was a lawyer. When asked how much money he wanted,he whispered in the interviewer's ear, "Three million dollars.""Why so much more than the other two?" he queried."Because,if I get $3 million, I'll give you $1 million, I'll keep $1 million, and we'll send the engineer!"
