From Kitabat.com (article by Jalil Ibrahim al-Mandilawi):
Three Iraqi contractors were bidding for a contract for the construction of a wall around a local municipal council. The first contractor proposed a bid of $1000 ($400 for construction materials, $400 for the laborers, and a profit of $200). The second contractor proposed $700 ($300 for materials, $300 for workers, and a profit of $100). The third contractor offered a bid of $2700. The head of the municipal council angrily asked the contractor why he proposed such a high bid. "It's very simple," said the contractor, smiling. "A thousand for me, a thousand for you, and we'll give the $700 to the second contractor to finish the job."
