A man returns from vacation and is feeling very ill. He goes to see his doctor and is immediately rushed to the Hospital to undergo a barrage of tests. After the tests, he wakes up in a private room at the hospital and the phone by his bed rings. "This is your doctor. We got the results back from your tests and we discovered that you have a very nasty virus that is extremely contagious!" "Oh my gosh," cried the man, "What are you going to do, doctor?" "Well, we're going to put you on a diet of pizza, pancakes, and pita bread." "Will that cure me?" asked the man. The doctor replied, "Well no, but...it's the only food we can get under the door."
