That Carnival Lines toilet-free cruise truly sounds like the worst trip ever:

Cruise Director John Heald said in comments posted in a blog on Carnival Lines website that the people aboard "have risen to the obvious challenges and difficult conditions onboard."
He said he's been making a lot of announcements from the bridge to keep everyone informed of the situation.
"Obviously it has been a challenge but let me tell you the most important facts and those are that the ship is safe, the guests are safe and that nobody was injured," he said.
Seth Grabel, 28, a Las Vegas magician, waited for his parents, who were on the cruise with hundreds of magicians participating in a convention put on by David Sandy Productions of St. Joseph, Mo.

A cruise is bad enough -- locked aboard a floating death-trap with people -- other people! -- with no means of escape. And then the ship stops. And the toilets stop working. And everything stinks like a sewer, which is a nice smell to smell when you're already possibly sea-sick. And then, worst of all, you find out that you're surrounded by magicians. What could be worse than a no-way-out floating sewage-smelling magician convention? The only thing I could think of is rectal surgery, or having to watch a performance of the Cirque de Soleil.
