A man returns from a trip to Shanghai and is feeling very ill.
He goes to see his doctor and is immediately rushed to the hospital to undergo a series of tests.

The man wakes up after these tests in a private room at the hospital
and the phone by his bed rings.
"This is your doctor," says the voice on the phone. "We have the
results back from your tests. I'm sorry to report that you have
an extremely contagious deadly disease known as G.A.S.H."
"G.A.S.H?" replies the man. "What in the hell is that?"

"It's a combination of Gonorrhea, AIDS, SARS, and Herpes,"
explains the doctor.

"My gosh, Doc!" screams the man in a panic, "what are we going to do?"

"Well we're going to put you on a strict diet of pizza, pancakes,
quesadillas, and pita bread," says the doctor matter-of-factly.

"Will that cure me?"

"Well, no," says the doctor, "but it's the only food that will fit
under the door."
