The occasion of a princess being hospitalized for severe morning sickness -- which brings about the risk of dehydration and other complications -- sure brought up a lot of jokes. Take a comment in a recent Gawker article on the hospital admission of pregnant Princess Kate Middleton:

Kinda funny. Of course, the crack is belittling to women who suffer from this condition and have such bad pregnancy-induced nausea that serious health problems are possible. But I digress. I'll let this CNN article on the condition and this first-person account of a husband with an ill wife do the explaining.
