Late Night Chenoweth Dreams Do Come True

With all of this talk about ABC comedy blocks, mo' medical dramas and the premiere of Jay Leno's prime time show, we've ignored one of the best weeks in Late Show history. Earlier this week, David Letterman hosted President Barack Obama and former president Bill Clinton and achieved his highest ratings in four years. Tonight, the host continues a great week by welcoming his employee Craig Ferguson and Movieline's favorite free agent Kristin Chenoweth.

The Late Show With David Letterman [11:35 PM, CBS]

The host of the best comedy-variety-absurd-cracked out-Anglo show on television makes his annual appearance on his boss's show, but this time he has stories about how crazy Americans are and his own strange past. Well, that's what Ferguson always brings to the table, but now he has a book, too. Songstress-for-hire Kristin Chenoweth brings up the rear (and opens the door to 1-3 self-deprecating jokes about Late Show not winning Emmys).

Grey's Anatomy [9 PM, ABC]

After the Flash Forward premiere at 8 PM, cry yourself through Grey's season six opener, easily the most heartbreaking episode in the series' history. Seattle Grace struggles to deal with the overwhelming grief after George's (T.R. Knight) death. Derek (Patrick Dempsey) receives a special offer from the hospital. The hour wouldn't be complete without an ER trauma, so cue the British backpacker who lost an appendage in a speedboat accident.

Saturday Night Live Weekend Update Thursday [8 PM, NBC]

Mentally prepare yourself for Megan Fox's previously unexplored sketch comedy skills this Saturday by watching this weekday dose of SNL. You can get a glimpse of this season's newest players during the prime-time take on news and politics.

The Skeleton Key [9 PM, Syfy]

My Netflix account has an automatic Kate Hudson filter that precludes any of her films (aside from Almost Famous) from finding its way into my queue. So imagine my surprise when when I saw this spooky New Orleans film in my suggestion box and liked it. Hudson carries the film as a hospice nurse assigned to an elderly woman (Gena Rowlands) with a dark past. John Hurt and Peter Sarsgaard co-star.
