Squee! It’s…

Ooh, double squee tonight. The brilliant William H. Macy returns to ER in their continuing self-congratulatory parade of former stars (eh, they survived 15  years–let ‘em have their parade. If it weren’t for Macy, we wouldn’t notice it going by anyway). Though perhaps best known for films such as Fargo, Boogie Nights, Seabiscuit, and Pleasantville, Macy’s won a boatload of awards for his work in TV movies like The Wool Cap and Door to Door and has been a guest on many well-known series. We, unsurprisingly, will always love him for stirring up trouble and then resolving it on Sports Night.

On Bones, Deirdre Lovejoy pops up as a US Attorney. You’ll remember Ms. Lovejoy not as part of the reverend’s family on The Simpsons, but from Eli Stone, Law & Order: Honey Barbecue Flavor, and the last great episode of The West Wing (“The Supremes”). We remember her most fondly, however, as another attorney: ADA Rhonda Pearlman on The Wire. Just thinking about her makes us happy, because Pearlman was one of the few characters who got an unobstructed happy ending (Cedric Daniels/Lance Reddick, rowr). She’s joining Bones for the return of the Gravedigger storyline; since that plot produced what might be the show’s finest episode (2006′s “Aliens in a Spaceship”), we expect all kinds of sparks to fly tonight. Bones appears on FOX at 8pm Eastern and Pacific; ER on NBC at 10.
