I went to see Letterman last night. It was pretty bad -- it airs on Friday! -- but there's a silver lining: Expect the wingnuts to complain loudly about Michael Keaton's potshots at blogs and Twitter.
Personally, I was not aware that Keaton was still alive, so his remarks were kinda funny on a number of levels.
...Oh, and there's a bit with Anderson Cooper and an orphanage that's really quite wonderful.
