On the heels of its Raymond lead-in, CBS's sitcom Two and a Half Men co-starring Charlie Sheen and Jon Cryer kicked off strong on Monday night with 18.1 million viewers. Meanwhile, NBC's drama Las Vegas got off to a so-so start with 12.6 million. But Nielsen's biggest casualty was Dubya. Monday Night Football and all those new TV shows crushed Brit Hume's A Conversation with the President, which scored Fox a paltry 4.3 million. That's worse than UPN's The Parkers! Of course, Mo'Nique is much cuter than Bush.
