An Arab was admitted in the Sheikh Rashid Hospital at Dubai for a heart transplant, but prior to the surgery the doctors needed to store his blood in case need arises. As the gentleman had a rare type of blood, it couldn't be found easily. So the call went out to a number of people of different nationality.
Finally a Malabari was located who had a similar type of blood. The Malabari willingly donated his blood for the Arab. After the surgery, the Arab sent the Malabari as appreciation for giving his blood, a new Toyota Prado, diamonds, lapiz lazuri jewellery, and a million US dollars.
Once again the Arab had to go through a corrective surgery. His doctor telephoned the Malabari who was more than happy to donate his blood again. After the second surgery, the Arab sent the Malabari a thank you card and a jar of Almond halwa sweets. The Malabari was shocked to see that the Arab this time did not reciprocate the Malabari's kind gesture as he had anticipated. He phoned the Arab and asked him that “this time also I thought that u would give me Toyota Prado, Diamonds and Jewellery.....But u gave only a card and a jar of Almond sweets!”

On this the Arab replied "My dear,.....now I have Mallu blood in my veins....
