Did David Letterman's apology go far enough?

David Letterman issued another apology to Sarah Palin and her family last night for making what he called a "coarse" and "beyond flawed" joke. In the nearly four minute segment, the late night talk show host appeared shaken as he further explained his original intention for the quip (which he thought he was making about Bristol Palin a young woman--and mother--of legal age) and acknowledged that this meant nothing compared to the public's increasingly skewed perception (many believed the highly sexual joke was in reference to Palin's 14-year-old daughter, Willow). Letterman said, "I told a bad joke. I told a joke that was beyond flawed, and my intent is completely meaningless compared to the perception. And since it was a joke I told, I feel that I need to do the right thing here and apologize for having told that joke. It's not your fault that it was misunderstood, it's my fault that it was misunderstood."

Was this rather gentlemanly and sincere apology enough? Too much? Can we all, for the love of all things holy, move on now, please?*
