Bet they only have about a trillion dollars in the bank.
See, Ian, may I call you Ian? Good. Well, Ian, you just don't comprehend the complex financial dealings of the super rich. Complex means hard to understand by the way, sorry. They may seem like they have a lot of money but really it's, what's that stuff you common folk put on your hovels? Wallpaper. That's it, wallpaper. It's all wallpaper and while they may have enough wallpaper to paper Mars (that's a planet), unfortunately using that wallpaper to buy things like football players or training grounds or even whole football clubs is a little silly, don't you think?
Glad we could have this chat.
