This ad caught me by complete surprise. I thought I was hallucinating when I first saw it. Why on earth would Dave do such a thing? Why would Jay? Was this post-production wizardry? Then I read the story behind it, and I realized it was a genius idea. It promotes The Late Show, while still helping Jay by showing that the animosity between these two guys can’t be all that bad if they are willing to sit on a sofa together and film this. Apparently this ad was top secret, and it was filmed at the Ed Sullivan theater, with both Oprah and Jay sneaking in while Dave was filming The Late Show to avoid suspicion. Take a look.
