A wealthy Arab sheik was admitted to hospital for heart surgery, but prior to the surgery, the doctors needed to store his type of blood in case the need arose.
As the gentleman had a rare type of blood, it couldn't be found locally, so, the call went out.
Finally a Scotsman was located who had a similar blood type. He willingly donated his blood for the Arab. After the surgery, the Arab sent the Scotsman, in appreciation for his giving his blood, a new BMW, a 5-carat diamonds and $50,000 dollars.
A couple of days later, once again, the Arab had to go through more corrective surgery.
The hospital telephoned the Scotsman who was more than happy to donate more of his blood again.
After the second surgery, the Arab sent the Scotsman a thank-you card and a box of Black Magic chocolates.
The Scotsman was shocked that the Arab did not reciprocate his kind gesture as he had before. He phoned the Arab and asked him: "I thought you would be generous again, that you would give me another BMW, diamonds and money ... but you only gave me a thank-you card and a box of chocolates."
"Aye laddie, replied the Scotsman - but I have Scottish blood in ma veins now".
