You will never see your own name as the Cash King. The name on top of the wheel is usually a friend (or a stranger) who has a lot of cash and who you will steal from the next time you land on Steal on the wheel! You cannot steal from yourself, and you probably don't want to be the Cash King because then you will be stolen from!
