An Arab Sheik was admitted to Abbott-Northwestern Hospital for heart surgery, but prior to the surgery, the doctors needed to store blood of his type 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 to the region. Finally a New London, Minnesota, Norwegian was located who had the right blood type. The Norwegian, whose name was Ole, willingly donated his blood for the Arab.

After the surgery, the Arab sent Ole, as appreciation for giving his blood, a new BMW, some diamonds & one million U.S. dollars. A couple of days later, once again, the Arab had to go through some corrective surgery. His doctor telephoned Ole who was more than happy to donate his blood again.

After the second surgery, the Arab sent Ole a thank-you card and five pounds of lutefisk.
Ole was shocked that time the Arab did not reciprocate with a new car, diamonds, and money. He phoned the Arab & said, "I thought dat you vould be yenerous again, and dat you vould give me anudder BMW, diamonds & money. But you only gave me a tank-you card & some lutefisk."

To this the Arab replied: "Ya, but now I haf Norvegian blood in my veins so I gotta tink tvice before I spend."
