This year I plan to be an IRS auditor.
Unlike ghosts, goblins, and poitergeists IRS auditors are real.
I think it's pretty scary if one day you're told that you're going to get a mega audit and you need to turn up the past seven years of records. Then they uncover all your indiscretions and make you pay, pay, and PAY.
At least it's original, and chances are no one else is going to do it.
I suppose another idea is to be the CEO of Enron, because he stole retirement money from many people.
For either all you need is a suit, a fedora (if you're the type to wear hats, otherwise don't worry about it), and the ability to dress well when being formal.
