Joke: A man returns to the U.S. from overseas and is feeling very ill. He goes to see his doctor, and is immediately rushed to the hospital, to undergo a barrage of extensive tests.The man wakes up after the tests in a private room at the hospital, and the phone by his bed rings."This is your doctor. We've had the results back from your tests and we've found you have an extremely nasty virus, which is extremely contagious!" "Oh my gosh," cries the man. He's in a panic now. "What are you going to do, doctor?" "Well we're going to put you on a diet of pizzas, pancakes, and pita bread." "Will that cure me?" asked the man hopefully. The doctor replied, "Well no, but ... it's the only food we can get under the door."
