I know, you've heard about this ad already, but I think it's worth posting here. Completely took me by surprise. Kudos on the secret behind the scenes maneuvers that had to happen to get this thing filmed. What's interesting to me – beyond the obvious "Dave and Jay are filming a commercial together?!?" – is the fact that this is an ad for The Late Show, which means Jay is in an ad plugging the competitor. I wonder if the two of them will talk about it tonight?
