Exit interview

There’s no one like Steve Carell of “The Office.” His last show is this week.

Guest-stars include Ray Romano, Ricky Gervais, Will Arnett, Catherine Tate and James Spader, all possible replacements for Carell (Ferrell is busy being a movie star). We rate their odds.

All that jazz

IT’S more than a year since Hurricane Katrina and the residents of Treme are trying to get by.

And Albert Lambreaux (Clarke Peters) is back to living on his insurance check.

Out at home

YANKEE Stadium — home to the New York Yankees for more than 80 years, and host to 37 World Series — is about to be demolished. And there’s no room for error when working within feet of a subway system that can’t stop running! The breakdown begins from the inside out as crews are first tasked with saving parts of the stadium — everything from the seats to the sod will be sold. Once the memorabilia salvage is over, the teams get straight to work clearing out the stadium. Kitchen equipment, light bulbs — it’s all got to go.
