Celebrities threatening to leave shows that put them at the top of their game for more money are as common in TV land as dollar bill Kleenex dispensers.

That's because it usually works. The star uses their awesome celebrity super powers to strike fear into the network heads' hearts (assuming they have one) and gets them to sign bigger and bigger checks, simply by threatening to walk. It's happened on almost every great show worth watching.

Now it's happened again. This time, 'Two and a Half Men' star Charlie Sheen wants out of his contract at the end of this season. Some say it's because of his recent chemical dependency and domestic disturbance problems. Others say he just wants more money. I say, call his bluff. Let the Sheenster run free.
