Finally, a Nigerian was located who had a similar type of blood. The Nigerian willingly donated his blood for the Arab. After the surgery, the Arab sent the Nigerian, as an appreciation, a new range rover sports car, diamonds, jewelries, and one million US dollars.
Once again, the Arab had to go through a corrective surgery. His doctor telephoned the Nigerian who was more than happy to donate his blood again. After a successful surgery, the Arab sent the Nigerian a thank you card and a box of cake and sweets.
The Nigerian was shocked to see that the Arab this time did not reciprocate his kind gesture as he had anticipated. He phoned the Arab and told him, "I thought this time you would give me a Hummer Jeep, Diamonds and Jewelries. But you gave me only a card and a box cake and sweets."
The Arab replied, "I can't help it, now I have Nigerian blood running in my veins."
