Unless you are a celebrity (e.g. Robert De Niro) or well known person (e.g. Bill Gates) you will have to wait in line like everyone else.
You gotta remember that Amex is a business. They are not just going to hand these cards out without its customers showing a proven loyalty to them. Also, they want to ensure that you have a good payment history with them for 12 months. They can't just take your word, or even your credit history's word for that matter, and just give you the card.
The Centurion isn't just any card, it's "the card" right now in pop culture, so you are going to have to earn one the hard way.
