World's Largest Floating Petri Dish

What do you get when you cruise on the world's largest cruise ship? Potentially the most sick passengers possible in one place:

MIAMI (Reuters) - Nearly 400 passengers and crew were sickened by a common stomach virus on a Caribbean cruise aboard Royal Caribbean's Freedom of the Seas, the world's largest cruise ship, the company said on Sunday.

It said 338 of the ship's 3,823 passengers and 46 of its 1,402 crew came down with what was believed to be a norovirus, a gastrointestinal ailment, brought on board by a passenger.

The ship returned to Miami on Sunday after completing a seven-day cruise to Mexico, the Cayman Islands, Jamaica and Haiti.

Cruising just doesn't sound like that much fun these days.
