In your finally Friday media column: Freakonomics is taking its bazillion readers away from the NYT, layoffs loom at the NY Daily News, Hollywood media wars aren't catty enough for Vanity Fair, and PBS must have news on the weekend.

For 13 years, actor Larry Anderson was the face of Scientology as star of the hilarious 40-minute conversion pic Orientation. Then he got out of the church. But what about the $150,000 he spent on E-meters and Scientology cruises?

Showtime's Secret Diary of a Call Girl was based on a series of bestselling books by anonymous prostitute Belle de Jour. How hot is this? Turns out she's a well-regarded British scientist, Dr. Brooke Magnanti. She came out last night.

Everyone is all mad at Steven Levitt and Stephen Dubner for including a hilariously wrong chapter on climate change in the sequel to their famous book Freakonomics, but some of us have been on the hating-those-dudes train forever.

Gawker Paycheck Journalism: doing our part to bring more money into circulation, or something. Because even the darkest cloud has a silver lining, every sex tape leak has an upside to it. In this case: product placement for Big eTobacco.

Your headline of the morning: "Politician Blames Neighborhood Crime on Pizza Sales."

Remember how Oprah once threatened to ruin the life of novelist Jonathan Franzen by selecting his book for her club and thereby making him lots and lots of money? Walmart might do the same to Apple's iPhone!

Freaknomics author Stephen Dubner says this is "The Best Paragraph You'll Read All Week." Really, Stephen Dubner? Perhaps you could use some more varied reading materials.

Some preliminary findings: "During warm weather holidays, Washington Park attracts a number of family reunions which also happen to drive up demand for prostitutes."

I-banker blogger Mijka Samora has done the math, and realized that hiring an illegal immigrant nanny, paying her lower wages, and paying her off the books "puts a cool $16,000 in after-tax dollars in your pocket every year." This "nanny arbitrage" is epidemic because, Mijka says, of "the widespread, if misguided, notion that 'everyone else does it', and in the conflicted satisfaction of helping an illegal make a living." But even though Mijka is obviously correct that monies saved by using cheap illegal labor are funneled back into the economy, his other arguments for why the city's fiscal infrastructure might come crumbling down if labor laws were actually enforced are less buyable.
