A man returns from a foreign holiday and is feeling very ill. He goes to see his doctor, and is immediately rushed to the hospital to undergo 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 STD called G.A.S.H. It's a combination of Gonorrhea, AIDS, Syphilis, and Herpes!"
"Oh my gosh," cried the man, "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.
"Well... no." The doctor replied. "But it's the only food we can get under the door."
