An Arab Sheik was admitted to hospital for heart surgery but, prior to the surgery, the doctors needed a store of his blood in case the need arose. As the gentleman had a rare blood type, it couldn't be found locally, so, the call went out to all the states. Finally a Scot was located who had a similar blood type. The Scot willingly donated his blood for the Arab. After the surgery, the Arab sent the Scotsman as appreciation for giving his blood, a new BMW, some diamonds and a stack of US dollars.
A couple of days later, once again, the Arab had to go through a corrective surgery. His doctor telephoned the Scotsman who was more than happy to donate his blood again. After the second surgery, the Arab sent the Scotsman a thank-you card & a jar of candies. The Scotsman was shocked that the Arab this time did not reciprocate his kind gesture as he had anticipated. He phoned the Arab and asked him: "I thought you would be generous again, that you would give me a BMW, diamonds and money... But you only gave me a thank-you card and a jar of candies".
To this the Arab replied: "Aye,but now I have Scottish blood in my veins".
