Also, see Michelle Malkin, "David Letterman: Perv" (via Memeorandum):
In November 2008, Letterman told tanking CBS News anchor Katie Couric that he was “aroused” by Gov. Palin.Also, don't miss Dan Riehl's report, "A Personal Story About David Letterman."
In March 2009, Letterman attacked Bristol Palin and snickered about her being “knocked up” again.
You know, David Letterman reminds me of the lecher at the school bus stop.
Or the aging creep lurking in the dirty magazine section at the 7-11.
Attention, CBS: Get him help now.
