You won't marry my sister

My sister thinks you're special because you're a King.
But in my eyes that doesn't mean a damn thing.
You have seven wives and you plan to make my sister number eight.
What you're doing is incredibly wrong, it's something that I hate.
You don't want to mess with me because I'm really pissed.
My sister is not going to become the wife of a Polygamist.
You are Royalty and you have a lot of money, you enjoy your success.
When you ask her to marry you, I'll make certain that she doesn't say yes.
You won't marry my sister, that's something I won't allow.
Get in your private jet and go back to your country now!
