What is Jay Leno Thinking?

Here's perhaps the strangest of yesterdays Super Bowl ads. I find this ad incredibly puzzling; but perhaps it speaks volumes about the incredible amount of damage Jay Leno has done to his reputation in the recent weeks regarding the ousting of Conan O'Brien as the host of 'The Tonight Show.' Leno - who will once again go head to head with David Letterman for late night supremacy - appears in a commercial for 'The Late Show with David Letterman?' Why would he do this? Letterman has spewed nothing but venom regarding Leno on his show recently, even saying "What you are seeing right now is classic Jay Leno" and went on to say how pleased he was that the public was getting to see what Jay is "really like." After these remarks, Leno then does a commercial for his rival; and a man who clearly doesn't respect him? On top of that, he appears with Oprah, which instantly brings to mind his PR-nightmare interview with Oprah where he came across as arrogant, dim-witted and an unsympathetic to Conan O'Brien and the whole ordeal. I have no clue what he's thinking to do this, other then perhaps he's been advised that it would make him look like a good sport. I think he looks like a moron.
