For vivid proof of the weakening dollar, look no further that the annual salary survey in the forthcoming issue of TV Guide: After two years of slumming alongside the likes of Zach Braff and seeing everyone from William Petersen ($600,000 per episode) to the Simpsons cast (each $400,000 per episode) pass him by, Charlie Sheen has reclaimed his spot at the top of the prime-time cash heap, earning $800,000 per 30-minute episode of Two and a Half Men. Granted, it's not seven-figure Friends money (which Sheen originally asked for in negotiations back in 2006), but we still think it bears repeating: Charlie Sheen makes $800,000 per episode of Two and a Half Men. Join us in getting our heads around it (and a few other hot-ticket raises) after the jump.

They've only been there since November, but Mariska Hargitay and her husband, actor Peter Hermann, are already putting their Chelsea penthouse on the market for $8.25 million in hopes of finding a better place uptown, closer to their son's private school. The O'Neill Building apartment they're leaving behind features three bedrooms, two terraces, and two floors of living space. More pics after the jump.

Actress Mariska Hargitay plays uptight detective Olivia Benson on Law & Order: Special Victims Unit.

"That's how she rolls. Just when you least expect it, Mariska throws you a curve. Over the years, I've come to expect nothing less from the hardest working—and needless to say, hottest—perp-buster on TV." That's from the "blog" of T.V. star Mariska Hargitay, which is written solely by people who are not Mariska Hargitay (but who may know her!). "Preorder your 'XO, M' t-shirts!" reads another "blog" post. It turns out that a lot of celebrity blogs aren't blogs at all, but just a collection of markedly amateurish press releases. But! At the other end of the spectrum, some celebrity blogs are deeply personal, like Al Roker's. He recently wrote a moving eulogy of his mom there! Its gravity is only slightly undermined by the cartoon of Al in a prop plane buzzing around the screen. So what else do famous people do with their personal webjournals? Our Intern Mary applied her analytical tools to the most recent posts on 48 of these sites and came up with some findings.

· Eddie Murphy is in talks to star in the Paramount comedy NowhereLand, though it's unclear from the project's brief description where the star's contractually mandated opportunity to disappear into a latex fat suit will come. [Variety]
