So much money

Now, just the other week there was news of big money in Hollywood. The main actor in the show House got a big pay increase. He's gonna be making like $9 million a year. And then there was news of the guys on Nip/Tuck. They are wanting more money too. As is the rest of the cast. Man, those people make a ton of money already! What do they need that much for anyhow?
