CBS

CBS and Warner Bros. say, "Based on the totality of Charlie Sheen's statements, conduct and condition, CBS and Warner Bros. Television have decided to discontinue production of 'Two and a Half Men' for the remainder of the season."

The decision comes several hours after TMZ posted a story in which Charlie Sheen challenged creator Chuck Lorre to a fight, calling him "a stupid, stupid little man and a pu**y punk that I never want to be like."

Sources connected with the production tell us ... Charlie's comments to TMZ were the final straw.

Here's the deal -- the bald guy who ate at Geisha House in Hollywood last night is ALSO named David Hasselhoff ... but he's a power technician from Texas.

Turns out ... Bald Hoff and German pop star Hoff are switching lives for a new CBS reality show -- in which celebs trade places with normal people who happen to share the same name.

Sources connected to the whole CBS megillah with Katie Couric tell TMZ Katie will probably jettison the evening news anchor chair for good, but not before the election.

Here's the lowdown. CBS hasn't delivered on any of the promises that lured Couric to the network in the first place -- generally, they said they would adjust the newscast to her skills, but in fact it's almost the same Metamucil broadcast as before. We're told she's frustrated and there is "strong interest" on the part of CNN, in particular to replace Mr. King when he retires.

We're also told several talk show syndicators have already contacted Couric's reps because they think she has enough heat to break into daytime. It's not a done deal that she'll choose CNN over talk, but right now both options are on the table.

As for the stories that CBS is pushing her out -- not true, because of two words: Les Moonves. He's been her guru and will let it all play out the way that's best for her. And, we're told CBS will continue to use Couric in other roles.
