Why Rosie won't go on Letterman

We've told you before about Rosie O'Donnell's blog, where she writes about her life, her kids, world problems, and everything else in bizarre poetry form. In her latest entry, she discusses why she won't go on The Late Show With David Letterman. I can't really summarize it in one paragraph. The thing has to be read in it's entirety. I will say, however, that the poem contains the phrases "I did a lot of umms" and "I doubt I would be comfy."
