Kathy Griffin hadn't been on David Letterman's show in 12 years, so she was raring to go last night.

She seemed a little nervous, but then again, so did Letterman… he'd just finished apologizing for making inappropriate jokes about Sarah Pailn's daughter. Anyway, Kathy made little jabs at "National Treasure" Dr. Maya Angelou, "scrappy" Katie Couric, and Governor Palin. Clip at left.
