Either way it sounds unpleasant. (I assume you mean the former.)
I heard a story on NPR a few days ago where a soldier was telling about trying to find [link|http://www.depend.com/products/products_male.asp|Depend] undergarments just before the Iraq invasion. It seems that the soldiers were worried about NBC attacks and the chance of not being able to use the toilet for several days....
Cheers,
