Letterman’s week-in-review video is pretty funny this week, including the “Beavis and Butthead” appearance I referenced in an earlier post.

By the way, Dave’s mock annoyance with Neil Patrick Harris is because there’s some sort of CBS promotional magazine called “Watch” — Dave hadn’t heard of it either — which had Harris on the cover, promoting his sitcom. Dave responded in mock outrage, demanding to know why the magazine had never done a cover or a story about him.

And (although you could probably figure this out) the young woman whose parents Dave inquires about is Rumer Willis, daughter of Bruce Willis and Demi Moore.
