If you've seen the by-now-infamous David Letterman/Oprah Winfrey/Jay Leno Super Bowl promo, then you are probably left with a lot of unanswered questions. "Were they really in the same room together?" "Did this happen before the Second Late Night Wars started?" "What about Conan?"

Well, the answer to the first two questions can be found in this New York Times article on the spot, which was shot last Tuesday. The short answer: Letterman just thought it would be funny. What would have been even funnier though, is if there had been four people on the couch. Because if there's anything more awkward than Leno and Letterman in a promo together, it would be throwing Conan into the mix. It turns out, that was exactly Letterman's original plan.

The first big Super Bowl shocker came early tonight, in a CBS promo, no less. The Super Bowl is on CBS, so it's no surprise we get a shot of David Letterman on a couch in his Colts jersey, but here's where things get weird: he's at a Super Bowl party with Oprah, and he's complaining about how it's the worst Super Bowl party ever.

We then see Jay freakin' Leno, who says that Letterman is only saying that because he's there. Letterman then mocks Leno, and then we see that this whole thing is a promo for 'The Late Show with David Letterman.'

How in the hell did this happen?
