The Wall Street Journal published the Best and Worst Jobs in the USA, based on a recently-released 2009 study. The list is based on five criteria: environment, income, employment outlook, physical demands and stress.
The methodology and the criteria used are limited and subjective. There really is no way to produce an accurate and objective list since best and worst are relative terms.
Take this list with a grain of salt and a big dose of humour. Just for fun, see where your job ranks.
