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.

Don't worry 'Two and a Half Men' fans. Your show is not ending any time soon.

Charlie Sheen will be released from rehab and resume taping new episodes of the long-running CBS sitcom as early as March 19.

The show went into a temporary hiatus towards the end of last month when Sheen had to check himself into rehab following his domestic abuse charges as a "precautionary measure." His charges and rehabilitation check-in sparked all sorts of speculation, including here at TV Squad, that his presence or lack thereof could grind the show to a halt, but it looks like that isn't the case ... for now.
