Engineers and Lawyers
There was once an engineer who found a magic lamp. When he rubbed it, a genie jumped out and said to him, "You have three wishes. But there is a catch - this wish system of mine was designed by a lawyer, so whatever you wish for every lawyer in the world will get double of!"
The engineer replied, "That's no problem, I can live with that." He then said, "For my first wish, I wish I had a Ferarri."
"OK", said the genie, and a Ferarri appeared in front of the engineer. "But remember, every lawyer in the world now has 2 Ferarris," the genie told the engineer.
The engineer remained unperturbed and said, "For my second wish, I wish for a million bucks." So a million bucks appeared in front of the engineer and the genie said, "remember, every lawyer in the world now has 2 million bucks."
The engineer was non-committal and then said, "I always wished I could donate a kidney!"
